But its progress is being hampered because a large part of process control is currently based on tacit knowledge, which is lost when plant operators retire. To offset this fading of knowledge, process variables must be quantified, because another change underway is the evident shift from conventional mass production to lean and green production, which promotes ordered production flow and rational process optimization by minimizing non-valueadded work. Both of these changes have affected the analysis of materials and necessitated in situ study of processes through their material properties. All the developed in situ methods in this thesis embody analysis of porous ceramics of different composition and pore structure, or the extent of added value in unfinished ceramic structures during powder compression [VII] and colloidal processing [V], in finished ceramic components in unsintered, high porosity fiber structures [I, III, VI], in ceramics composed of sintered, low porosity solids [II], and in oriented, lamellar structures [IV]. From the materials science perspective, the study of these porous ceramics provides information on their mechanical behavior in relation to pore structure: the effect of porosity changes in powder structure [VII], the effect of sintering in fibrous structure [III], and the effect of pore orientation in lamellar structure [IV]. The second investigated regime is the behavior of electrical signals in a porous material in sintered structure [II], and in suspensions [V]. Third regime is the investigation of local permeability of a fibrous structure [I, VI]. Whereas this thesis work focused mostly on the concrete development of 6 different characterization methods-thermal flow permeametry, grit blast-analysis, electrical pore analysis, adaptive image analysis, and granule bed compression-the results in the introduction demonstrate a systematic approach to developing process integrable in situ methods and discuss the relative importance of the methods' robustness, integrability, reliability, and comprehensiveness. In the regime of materials science, this work contributes to the analysis of pore characteristics and the effects of pores by showing results of granule bed strength measurement, the effect of the pore parameter on compressive strength, the concept of fiber free length, and a strong hypothesis about the reactions of material interfaces with electrical signals. iii Preface I've understood that everything can be predicted with a hundred percent certainty given that all the variables are known (Laplace's demon). My take on this are the in situ methods that measure some occurrences better than anything there was before them. Still, I do not claim to understand the real world very well, but have made it more predictable. This has not been my thrive in personal life as I like surprises but the industrial processes are better without them. About the publications Articles [I, III, VI] are based on experiments done in a project that was funded by a customer. The project was carried out during 2010-2014 and aimed to increase the understanding of variables that dominate the lifespan of fibrous hot gas filter elements, which are industrially used. A secondary objective was to develop methods, such as those published, which could be used to analyze the remaining lifetime. Articles [II, V] are based on experiments done in a project that was carried out during 2012-2014 and funded by the Finnish Funding Agency for Innovation (TEKES) and steered by Finnish industrial partners Nordkalk, IDO and Outotec. The project focused on material responses to a multifrequency signal and aimed to develop on site methods for analysis of industrially produced or industrially used products measuring the functioning of filters, drying of ceramics, homogeneity of powders, and porosity and specific surface area of materials. Article [IV] is a collaborative effort with the main author from Stockholm University. Article [VII] is based on the development of a method directly funded by an industrial customer. Because all the industrially funded work was carried out under a non-disclosure agreement, the names of some companies, their processes, and the producers of the studied materials cannot be revealed.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="311408e22a1d4fef1ad29f0294fee2dc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940514,"asset_id":109980788,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940514/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980788"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980788"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980788;

There are several limitations in the existing characterization methods, so new techniques are required to meet the increasing demands of analysis. This paper examines the possible use of an electrical frequency-response method based on broadband excitation and Fourier techniques to characterize porous ceramic materials. The applied method provides a non-destructive, online characterization technique that is fast and can be applied inexpensively. In this article, ceramic samples with three different pore characteristics were measured by the frequency-response method that used a pseudo-random binary sequence. A sample of material was placed between the plates of a capacitor, and the capacitance was measured. Material properties, such as porosity, influence the permittivity value of the material. The samples with different porosities can be distinguished by analyzing the capacitance of the capacitor.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="59dbec8868a43486fd6e9e92bf65b538" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940513,"asset_id":109980787,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940513/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980787"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980787"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980787;

Polysaccharides are dissolved in liquids, such as water, in many industrial products, like paints, cosmetics and culinary products. In these products, it is important to control viscosity or create thixotropy and yield stress for product functionality. Electromagnetic field and electrical conductivity techniques were applied to a meter polysaccharide dissolution process online up to a 0.5 wt% concentration, and the resultant solution was also further tested by UV–Vis spectrophotometry. The electromagnetic field technique measures changes in the local electrical permittivity of the liquid and the interest in this research were to find out whether the changes correlate to the concentration changes during the dissolution of polymer polysaccharide. The results that were obtained showed good consistency, suggesting the feasibility of the electromagnetic field technique in on...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5ca032341e3a7bdf6402a7e9723fb208" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940483,"asset_id":109980777,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940483/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980777"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980777"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980777;

Additive manufacturing, a technology capable of forming intricate geometries, was seen as a potential method to form porous adsorption structures. Stereolithography was chosen as the fabrication method for hierarchically porous zeolite structures because of its high resolution and superior forming capability. The focus of this study was on tailoring the properties of light-cured resin to maximize stability during shaping and shape retention in the debinding stage. Successful slurry preparation was required for demonstrating that monoliths with channel geometry and retained adsorption properties can be manufactured with stereolithography. The final printed structures exhibited hierarchical porosity consisting of flow channels, macropores between the primary particles and the characteristic microporosity of zeolite framework. The structure was manufactured by using blue light to cure layers of resin containing ZSM-5 zeolite. An appropriate debinding heat-treatment cycle was generated based on the TGA and DSC thermal analysis results. The properties of the porous structure were analysed by comparing the BET surface area, XRD patterns and SEM images of as-received powder and a debound piece. The measured BET adsorption properties of the final monoliths remained comparable to the as-received ZSM-5 powder. Based on this study, stereolithography can be utilized to manufacture porous zeolite structures.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="0b7a34654f1904f1ce7c4cae3361a293" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940495,"asset_id":109980773,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940495/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980773"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980773"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980773;

Friction behaviour of irregularly rough steel against CSM-rubber in water-lubricated contact at a velocity range of 1.7-17 m/s was investigated. A noticeable friction maximum was observed near the midpoint of the range extremities, at 6.7-8.3 m/s, and the resulting wear marks on steel specimens also suggested the highest severity of contact at these medium speeds. Higher end of sliding velocity range returned friction to lower levels and less wear was observed. This was interpreted as a product of reduction in frictional heat due to slight improvement in mixed lubrication. In conclusion, the peculiar friction behaviour was interpreted as a system-specific anomaly, implying that similar problematics could be encountered in other rubber wheel wear test systems as well.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="d27f65ae227909ccf65af9d3bdd1b3fa" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940496,"asset_id":109980772,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940496/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980772"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980772"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980772;

Photocatalytic activity can be exploited in the decomposition of hazardous pollutants from environment. In this study, we produced zinc oxide thin films on stainless steel plates by hydrothermal method varying the precursor concentration (from 0.029 M to 0.16 M) and the synthesis temperature (from 70˚C to 90 ˚C). Morphology of the synthesized films was examined using field-emission scanning electron microscopy (FESEM) and photocatalytic activity of the films was characterized using methylene blue decomposition tests. It was found that the morphology of the nanostructures was strongly affected by the precursor concentration and the temperature of the synthesis. At lower concentrations zinc oxide grew as thin needlelike nanorods of uniform length and shape and aligned perpendicular to the stainless steel substrate surface. At higher concentrations the shape of the rods transformed towards hexagon shaped units and further on towards flaky platelets. Temperature changes caused variations in the coating thickness and the orientation of the crystal units. It was also observed, that the photocatalytic activity of the prepared films was clearly dependent on the morphology of the surfaces.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6ef4e3cc65f9060a2c90f64be60382a6" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940479,"asset_id":109980770,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940479/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980770"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980770"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980770;

The durability of the formed granules is a crucial parameter, typically evaluated by the compressive strength of the granules. However, especially for granules with a diameter in the order of tens of microns, statistically relevant testing of individual granules is not a feasible alternative, and in such cases uniaxial bed compression is required. There has not been consensus on whether uniaxial compression of a granule bed can be used to study the fracture of micron size or brittle granules. In our case study of a bed of sintered kaolinite granules with diameters under 100 μm, we show how the compressive strength of individual granules can be obtained from the compressive measurement of the entire bed by plotting the relative density versus the logarithmic pressure scale. We compressed the kaolinite powder with different loads; microscopy confirmed that below the analyzed strength the granules are intact, though the granules start to fracture in the curved region on the compression curve. We found that angle-fitting can be used to locate the average compressive strength on the compression curve and to follow the evolution of strength with sintering temperature. The experiments in unison demonstrate that compression curve analysis is applicable for strength analysis of brittle granules.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980769"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980769"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980769;

Yet, this can play an important role affecting characteristics, such as, fluid flow property, strength and heat conductivity. This article presents a method named thermal flow permeametry (TFP) that is applicable for a quick analysis of variations in flow channels, even in meter-sized structures. For illustrating the method, we analyzed the local permeability levels of a large and extremely complex fiber structure. In TFP, hot air is ejected through a structure, while thermal camera measures local surface temperature variations during heating. Gray values of the thermal image are then plotted versus the structures local thickness, density and permeability. We showed that gray values link with local permeability, affected by thickness, density and flow channel tortuousness. We also found out that TFP is very sensitive to local changes in flow channels.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980768"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980768"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980768; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=109980768]").text(description); $(".js-view-count[data-work-id=109980768]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 109980768; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='109980768']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=109980768]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":109980768,"title":"Thermal flow permeametry – A rapid method for finding local changes in flow channels","internal_url":"https://www.academia.edu/109980768/Thermal_flow_permeametry_A_rapid_method_for_finding_local_changes_in_flow_channels","owner_id":34176091,"coauthors_can_edit":true,"owner":{"id":34176091,"first_name":"Matti","middle_initials":null,"last_name":"Järveläinen","page_name":"MattiJärveläinen","domain_name":"independent","created_at":"2015-08-24T02:16:17.245-07:00","display_name":"Matti Järveläinen","url":"https://independent.academia.edu/MattiJ%C3%A4rvel%C3%A4inen"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="109980767"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/109980767/Mechanical_performance_and_CO2_uptake_of_ion_exchanged_zeolite_A_structured_by_freeze_casting"><img alt="Research paper thumbnail of Mechanical performance and CO2 uptake of ion-exchanged zeolite A structured by freeze-casting" class="work-thumbnail" src="https://attachments.academia-assets.com/107940497/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/109980767/Mechanical_performance_and_CO2_uptake_of_ion_exchanged_zeolite_A_structured_by_freeze_casting">Mechanical performance and CO2 uptake of ion-exchanged zeolite A structured by freeze-casting</a></div><div class="wp-workCard_item"><span>Journal of the European Ceramic Society</span><span>, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Zeolite 4A has been freeze-cast into highly porous monoliths with a cylindrical shape.

The brittle monoliths, with lamellar or columnar pores and wall thicknesses between 8 and 35 m, show a compressive mechanical response along the main pore axis that could be modeled by a buckling behavior. The failure strength is proportional to the density and the amount of transverse bridging across lamella, which was shown to be related to the pore cross-sectional aspect ratio. Monoliths with highly anisotropic pores with a cross-sectional aspect ratio higher than 3 yielded sequentially from the top surface, whereas monoliths with a pore aspect ratio lower than 3 were found to delaminate into longitudinal splinters. The freeze-cast monoliths show a sharp gas breakthrough front with a 1:9 mixture of CO 2 and N 2 , indicating rapid uptake kinetics of the lamellar structures.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="3d2eab13cd7cf47a170334c91ff708ff" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940497,"asset_id":109980767,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940497/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980767"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980767"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980767;

A reason for the difficulty in this task has been the lack of a fast and reliable measurement. In this study, we tested the measurement of particle suspension by using a method based on a passive resonance sensor. The relative amounts of dispersing agent and aluminium oxide in the suspension were varied. The studied method yielded signals which depended on the complex permittivity of the suspension. The results indicated that we were able to measure information that can be used as feedback for the suspension preparation process. In addition, the tested instrumentation was simple and robust and thus this method may allow online measurements directly from the industrial processes.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980764"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980764"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980764; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=109980764]").text(description); $(".js-view-count[data-work-id=109980764]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 109980764; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='109980764']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=109980764]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":109980764,"title":"Passive resonance sensor based method for monitoring particle suspensions","internal_url":"https://www.academia.edu/109980764/Passive_resonance_sensor_based_method_for_monitoring_particle_suspensions","owner_id":34176091,"coauthors_can_edit":true,"owner":{"id":34176091,"first_name":"Matti","middle_initials":null,"last_name":"Järveläinen","page_name":"MattiJärveläinen","domain_name":"independent","created_at":"2015-08-24T02:16:17.245-07:00","display_name":"Matti Järveläinen","url":"https://independent.academia.edu/MattiJ%C3%A4rvel%C3%A4inen"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="109980762"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/109980762/Mechanical_Characterization_of_Fiber_Ceramics_Effect_of_Temperature_"><img alt="Research paper thumbnail of Mechanical Characterization of Fiber Ceramics: Effect of Temperature**" class="work-thumbnail" src="https://attachments.academia-assets.com/107940494/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/109980762/Mechanical_Characterization_of_Fiber_Ceramics_Effect_of_Temperature_">Mechanical Characterization of Fiber Ceramics: Effect of Temperature**</a></div><div class="wp-workCard_item"><span>Advanced Engineering Materials</span><span>, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">MSc.

But its progress is being hampered because a large part of process control is currently based on tacit knowledge, which is lost when plant operators retire. To offset this fading of knowledge, process variables must be quantified, because another change underway is the evident shift from conventional mass production to lean and green production, which promotes ordered production flow and rational process optimization by minimizing non-valueadded work. Both of these changes have affected the analysis of materials and necessitated in situ study of processes through their material properties. All the developed in situ methods in this thesis embody analysis of porous ceramics of different composition and pore structure, or the extent of added value in unfinished ceramic structures during powder compression [VII] and colloidal processing [V], in finished ceramic components in unsintered, high porosity fiber structures [I, III, VI], in ceramics composed of sintered, low porosity solids [II], and in oriented, lamellar structures [IV]. From the materials science perspective, the study of these porous ceramics provides information on their mechanical behavior in relation to pore structure: the effect of porosity changes in powder structure [VII], the effect of sintering in fibrous structure [III], and the effect of pore orientation in lamellar structure [IV]. The second investigated regime is the behavior of electrical signals in a porous material in sintered structure [II], and in suspensions [V]. Third regime is the investigation of local permeability of a fibrous structure [I, VI]. Whereas this thesis work focused mostly on the concrete development of 6 different characterization methods-thermal flow permeametry, grit blast-analysis, electrical pore analysis, adaptive image analysis, and granule bed compression-the results in the introduction demonstrate a systematic approach to developing process integrable in situ methods and discuss the relative importance of the methods' robustness, integrability, reliability, and comprehensiveness. In the regime of materials science, this work contributes to the analysis of pore characteristics and the effects of pores by showing results of granule bed strength measurement, the effect of the pore parameter on compressive strength, the concept of fiber free length, and a strong hypothesis about the reactions of material interfaces with electrical signals. iii Preface I've understood that everything can be predicted with a hundred percent certainty given that all the variables are known (Laplace's demon). My take on this are the in situ methods that measure some occurrences better than anything there was before them. Still, I do not claim to understand the real world very well, but have made it more predictable. This has not been my thrive in personal life as I like surprises but the industrial processes are better without them. About the publications Articles [I, III, VI] are based on experiments done in a project that was funded by a customer. The project was carried out during 2010-2014 and aimed to increase the understanding of variables that dominate the lifespan of fibrous hot gas filter elements, which are industrially used. A secondary objective was to develop methods, such as those published, which could be used to analyze the remaining lifetime. Articles [II, V] are based on experiments done in a project that was carried out during 2012-2014 and funded by the Finnish Funding Agency for Innovation (TEKES) and steered by Finnish industrial partners Nordkalk, IDO and Outotec. The project focused on material responses to a multifrequency signal and aimed to develop on site methods for analysis of industrially produced or industrially used products measuring the functioning of filters, drying of ceramics, homogeneity of powders, and porosity and specific surface area of materials. Article [IV] is a collaborative effort with the main author from Stockholm University. Article [VII] is based on the development of a method directly funded by an industrial customer. Because all the industrially funded work was carried out under a non-disclosure agreement, the names of some companies, their processes, and the producers of the studied materials cannot be revealed.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="311408e22a1d4fef1ad29f0294fee2dc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940514,"asset_id":109980788,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940514/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980788"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980788"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980788;

There are several limitations in the existing characterization methods, so new techniques are required to meet the increasing demands of analysis. This paper examines the possible use of an electrical frequency-response method based on broadband excitation and Fourier techniques to characterize porous ceramic materials. The applied method provides a non-destructive, online characterization technique that is fast and can be applied inexpensively. In this article, ceramic samples with three different pore characteristics were measured by the frequency-response method that used a pseudo-random binary sequence. A sample of material was placed between the plates of a capacitor, and the capacitance was measured. Material properties, such as porosity, influence the permittivity value of the material. The samples with different porosities can be distinguished by analyzing the capacitance of the capacitor.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="59dbec8868a43486fd6e9e92bf65b538" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940513,"asset_id":109980787,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940513/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980787"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980787"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980787;

Polysaccharides are dissolved in liquids, such as water, in many industrial products, like paints, cosmetics and culinary products. In these products, it is important to control viscosity or create thixotropy and yield stress for product functionality. Electromagnetic field and electrical conductivity techniques were applied to a meter polysaccharide dissolution process online up to a 0.5 wt% concentration, and the resultant solution was also further tested by UV–Vis spectrophotometry. The electromagnetic field technique measures changes in the local electrical permittivity of the liquid and the interest in this research were to find out whether the changes correlate to the concentration changes during the dissolution of polymer polysaccharide.

Hierarchy in adsorbents offers flow channels on different scales, resulting in fast gas flow into a structure. Additive manufacturing, a technology capable of forming intricate geometries, was seen as a potential method to form porous adsorption structures. Stereolithography was chosen as the fabrication method for hierarchically porous zeolite structures because of its high resolution and superior forming capability. The focus of this study was on tailoring the properties of light-cured resin to maximize stability during shaping and shape retention in the debinding stage. Successful slurry preparation was required for demonstrating that monoliths with channel geometry and retained adsorption properties can be manufactured with stereolithography. The final printed structures exhibited hierarchical porosity consisting of flow channels, macropores between the primary particles and the characteristic microporosity of zeolite framework. The structure was manufactured by using blue light to cure layers of resin containing ZSM-5 zeolite. An appropriate debinding heat-treatment cycle was generated based on the TGA and DSC thermal analysis results. The properties of the porous structure were analysed by comparing the BET surface area, XRD patterns and SEM images of as-received powder and a debound piece. The measured BET adsorption properties of the final monoliths remained comparable to the as-received ZSM-5 powder. Based on this study, stereolithography can be utilized to manufacture porous zeolite structures.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="0b7a34654f1904f1ce7c4cae3361a293" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940495,"asset_id":109980773,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940495/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980773"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980773"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980773;

Friction behaviour of irregularly rough steel against CSM-rubber in water-lubricated contact at a velocity range of 1.7-17 m/s was investigated. A noticeable friction maximum was observed near the midpoint of the range extremities, at 6.7-8.3 m/s, and the resulting wear marks on steel specimens also suggested the highest severity of contact at these medium speeds. Higher end of sliding velocity range returned friction to lower levels and less wear was observed. This was interpreted as a product of reduction in frictional heat due to slight improvement in mixed lubrication. In conclusion, the peculiar friction behaviour was interpreted as a system-specific anomaly, implying that similar problematics could be encountered in other rubber wheel wear test systems as well.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="d27f65ae227909ccf65af9d3bdd1b3fa" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940496,"asset_id":109980772,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940496/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980772"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980772"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980772;

Photocatalytic activity can be exploited in the decomposition of hazardous pollutants from environment. In this study, we produced zinc oxide thin films on stainless steel plates by hydrothermal method varying the precursor concentration (from 0.029 M to 0.16 M) and the synthesis temperature (from 70˚C to 90 ˚C). Morphology of the synthesized films was examined using field-emission scanning electron microscopy (FESEM) and photocatalytic activity of the films was characterized using methylene blue decomposition tests. It was found that the morphology of the nanostructures was strongly affected by the precursor concentration and the temperature of the synthesis. At lower concentrations zinc oxide grew as thin needlelike nanorods of uniform length and shape and aligned perpendicular to the stainless steel substrate surface. At higher concentrations the shape of the rods transformed towards hexagon shaped units and further on towards flaky platelets. Temperature changes caused variations in the coating thickness and the orientation of the crystal units. It was also observed, that the photocatalytic activity of the prepared films was clearly dependent on the morphology of the surfaces.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6ef4e3cc65f9060a2c90f64be60382a6" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":107940479,"asset_id":109980770,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/107940479/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980770"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980770"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980770;

The durability of the formed granules is a crucial parameter, typically evaluated by the compressive strength of the granules. However, especially for granules with a diameter in the order of tens of microns, statistically relevant testing of individual granules is not a feasible alternative, and in such cases uniaxial bed compression is required. There has not been consensus on whether uniaxial compression of a granule bed can be used to study the fracture of micron size or brittle granules. In our case study of a bed of sintered kaolinite granules with diameters under 100 μm, we show how the compressive strength of individual granules can be obtained from the compressive measurement of the entire bed by plotting the relative density versus the logarithmic pressure scale. We compressed the kaolinite powder with different loads; microscopy confirmed that below the analyzed strength the granules are intact, though the granules start to fracture in the curved region on the compression curve. We found that angle-fitting can be used to locate the average compressive strength on the compression curve and to follow the evolution of strength with sintering temperature. The experiments in unison demonstrate that compression curve analysis is applicable for strength analysis of brittle granules.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980769"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980769"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980769;

Yet, this can play an important role affecting characteristics, such as, fluid flow property, strength and heat conductivity. This article presents a method named thermal flow permeametry (TFP) that is applicable for a quick analysis of variations in flow channels, even in meter-sized structures. For illustrating the method, we analyzed the local permeability levels of a large and extremely complex fiber structure. In TFP, hot air is ejected through a structure, while thermal camera measures local surface temperature variations during heating. Gray values of the thermal image are then plotted versus the structures local thickness, density and permeability. We showed that gray values link with local permeability, affected by thickness, density and flow channel tortuousness. We also found out that TFP is very sensitive to local changes in flow channels.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980768"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980768"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980768; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=109980768]").text(description); $(".js-view-count[data-work-id=109980768]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 109980768; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='109980768']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=109980768]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":109980768,"title":"Thermal flow permeametry – A rapid method for finding local changes in flow channels","internal_url":"https://www.academia.edu/109980768/Thermal_flow_permeametry_A_rapid_method_for_finding_local_changes_in_flow_channels","owner_id":34176091,"coauthors_can_edit":true,"owner":{"id":34176091,"first_name":"Matti","middle_initials":null,"last_name":"Järveläinen","page_name":"MattiJärveläinen","domain_name":"independent","created_at":"2015-08-24T02:16:17.245-07:00","display_name":"Matti Järveläinen","url":"https://independent.academia.edu/MattiJ%C3%A4rvel%C3%A4inen"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="109980767"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/109980767/Mechanical_performance_and_CO2_uptake_of_ion_exchanged_zeolite_A_structured_by_freeze_casting"><img alt="Research paper thumbnail of Mechanical performance and CO2 uptake of ion-exchanged zeolite A structured by freeze-casting" class="work-thumbnail" src="https://attachments.academia-assets.com/107940497/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/109980767/Mechanical_performance_and_CO2_uptake_of_ion_exchanged_zeolite_A_structured_by_freeze_casting">Mechanical performance and CO2 uptake of ion-exchanged zeolite A structured by freeze-casting</a></div><div class="wp-workCard_item"><span>Journal of the European Ceramic Society</span><span>, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Zeolite 4A has been freeze-cast into highly porous monoliths with a cylindrical shape.

The failure strength is proportional to the density and the amount of transverse bridging across lamella, which was shown to be related to the pore cross-sectional aspect ratio. Monoliths with highly anisotropic pores with a cross-sectional aspect ratio higher than 3 yielded sequentially from the top surface, whereas monoliths with a pore aspect ratio lower than 3 were found to delaminate into longitudinal splinters.

A reason for the difficulty in this task has been the lack of a fast and reliable measurement. In this study, we tested the measurement of particle suspension by using a method based on a passive resonance sensor. The relative amounts of dispersing agent and aluminium oxide in the suspension were varied. The studied method yielded signals which depended on the complex permittivity of the suspension. The results indicated that we were able to measure information that can be used as feedback for the suspension preparation process. In addition, the tested instrumentation was simple and robust and thus this method may allow online measurements directly from the industrial processes.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980764"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980764"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980764; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=109980764]").text(description); $(".js-view-count[data-work-id=109980764]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 109980764; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='109980764']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=109980764]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":109980764,"title":"Passive resonance sensor based method for monitoring particle suspensions","internal_url":"https://www.academia.edu/109980764/Passive_resonance_sensor_based_method_for_monitoring_particle_suspensions","owner_id":34176091,"coauthors_can_edit":true,"owner":{"id":34176091,"first_name":"Matti","middle_initials":null,"last_name":"Järveläinen","page_name":"MattiJärveläinen","domain_name":"independent","created_at":"2015-08-24T02:16:17.245-07:00","display_name":"Matti Järveläinen","url":"https://independent.academia.edu/MattiJ%C3%A4rvel%C3%A4inen"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="109980762"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/109980762/Mechanical_Characterization_of_Fiber_Ceramics_Effect_of_Temperature_"><img alt="Research paper thumbnail of Mechanical Characterization of Fiber Ceramics: Effect of Temperature**" class="work-thumbnail" src="https://attachments.academia-assets.com/107940494/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/109980762/Mechanical_Characterization_of_Fiber_Ceramics_Effect_of_Temperature_">Mechanical Characterization of Fiber Ceramics: Effect of Temperature**</a></div><div class="wp-workCard_item"><span>Advanced Engineering Materials</span><span>, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">MSc.

This article presents a method that is applicable for a quick analysis of flow distribution even with large samples. In this first attempt to understand how our flow distribution thermal imaging works, we present how the measuring parameters and the results correlate with sample&amp;#39;s thickness and density. The results indicate that our method can quickly make a distinction between areas that have different flow resistances because of variations in the sample&amp;#39;s density or wall thickness.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="109980761"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="109980761"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 109980761;
