In this methodology, random liquid fluctuating velocities are used as direct input into the drag model. The specific aim of this study is to directly compute the granular pressure in a liquid fluidized bed. The granular pressure is defined using the particle-wall collision frequency and the corresponding particle momentum transport during the collision. Initially, we validated our model by comparing the relationship between superficial fluid velocity and bed expansion against the well-known Richardson-Zaki [1] equation. The results demonstrated a good agreement of our model. The granular pressure and temperature, as well as the particle-wall collision frequency, in the liquid fluidized bed were determined for superficial fluid velocities in the range between 0.08 and 0.32 m/s.

The microfluidic method overcomes the inherent uncertainties in conventional large-scale devices and methods.","owner":{"id":132470,"first_name":"Geoffrey","middle_initials":null,"last_name":"Evans","page_name":"GeoffreyEvans","domain_name":"newcastle-au","created_at":"2010-02-14T19:05:27.687-08:00","display_name":"Geoffrey Evans","url":"https://newcastle-au.academia.edu/GeoffreyEvans"},"attachments":[{"id":95602180,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/95602180/thumbnails/1.jpg","file_name":"J276BubbleCoalescence.pdf","download_url":"https://www.academia.edu/attachments/95602180/download_file?st=MTczMzkyMDA3Myw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"A_Microfluidic_Method_for_Investigating.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/95602180/J276BubbleCoalescence-libre.pdf?1670801649=\u0026response-content-disposition=attachment%3B+filename%3DA_Microfluidic_Method_for_Investigating.pdf\u0026Expires=1733923673\u0026Signature=VAI2cFNXovmDPD-jEK8x6xrXbFdIri6zWgQ1Vs6Xw7aiQpOfj4Vl-zIly8v0ddVW6nQYrzzZrMl-B6p2mWPeiDzaOA-iX-pqno8F~fozt0bM4gfopPfBQJW~bkHfegtXIvPNp8aeEf2ct5DTQaf8lp6~8~108Sxx4sdAmUvOTVYttATjOOuWjEIEd0~LSpbPxG7NSguvCKce1I6M2REUlLTqXvF6d2SBbqKqquc~6~DoMOIAKJo9DcSUTYPr8pdd9IdjUJaM2c4BkWqeilkLsQWomeeyr5UXGZAJdiJjFC0UwNgwoa2bbEysKM98xUJPMxa0~PMdNohiQtXAgkv0gg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":505,"name":"Condensed Matter Physics","url":"https://www.academia.edu/Documents/in/Condensed_Matter_Physics"},{"id":511,"name":"Materials Science","url":"https://www.academia.edu/Documents/in/Materials_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":2166,"name":"Surfaces and Interfaces","url":"https://www.academia.edu/Documents/in/Surfaces_and_Interfaces"},{"id":2721,"name":"Microfluidics","url":"https://www.academia.edu/Documents/in/Microfluidics"},{"id":4748,"name":"Electrochemistry","url":"https://www.academia.edu/Documents/in/Electrochemistry"},{"id":5427,"name":"Spectroscopy","url":"https://www.academia.edu/Documents/in/Spectroscopy"},{"id":16217,"name":"Halide","url":"https://www.academia.edu/Documents/in/Halide"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary"},{"id":152114,"name":"Bubble","url":"https://www.academia.edu/Documents/in/Bubble"},{"id":283531,"name":"Microchannel","url":"https://www.academia.edu/Documents/in/Microchannel"},{"id":348756,"name":"Ion","url":"https://www.academia.edu/Documents/in/Ion"},{"id":743666,"name":"Langmuir","url":"https://www.academia.edu/Documents/in/Langmuir"}],"urls":[{"id":26908231,"url":"https://pubs.acs.org/doi/pdf/10.1021/acs.langmuir.6b03266"}]}, 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="92650139"><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/92650139/Evaporation_of_ethanol_water_binary_mixture_sessile_liquid_marbles"><img alt="Research paper thumbnail of Evaporation of ethanol-water binary mixture sessile liquid marbles" class="work-thumbnail" src="https://attachments.academia-assets.com/95602182/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/92650139/Evaporation_of_ethanol_water_binary_mixture_sessile_liquid_marbles">Evaporation of ethanol-water binary mixture sessile liquid marbles</a></div><div class="wp-workCard_item"><span>Langmuir : the ACS journal of surfaces and colloids</span><span>, Jun 26, 2016</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Numerous works have been reported on the evaporation of a sessile liquid marble, a liquid droplet...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Numerous works have been reported on the evaporation of a sessile liquid marble, a liquid droplet coated with particles, through geometric measurements.

The collision interaction between a suspended liquid (water) film of thickness 3.41 6 0.04 mm and an impacting hydrophilic particle (glass ballotini) of different diameters (1.1-3.0 mm) in low particle impact Weber number (We 5 q l v 2 p d p =r) range (1.4-33) is reported. Two distinct outcomes were observed-particle retention in the film at lower Weber number and complete penetration of the film toward higher Weber number cases. A collision parameter was defined based on energy balance approach to demarcate these two interaction regimes which agreed reasonably well with the experimental outcomes. It was shown that the liquid ligament forming in the complete penetration cases breaks up purely by \"dripping/end pinch-off\" mechanism and not due to capillary wave instability. An analytical model based on energy balance approach was proposed to determine the liquid mass entrainment associated with the ligament which compared well with the experimental measurements. A good correlation between the %film mass entrained and the particle Bond number (Bo 5 q l gd 2 p =r) was obtained which indicated a dependency of Bo 1.72. Computationally, a three-dimensional CFD model was developed to simulate these interactions using different contact angle boundary conditions which in general showed reasonable agreement with experiment but also indicated deficiency of a constant contact angle value to depict the interaction physics in entirety.

In the model, the random Brownian diffusion and the externally induced dielectrophoresis (DEP) motion were considered as the driving mechanisms for the transport of particles in colloidal suspension. To simulate particle interactions, the non-contact surface force and the contact force were taken into account using the well-known Derjaguin-Landau-Verway-Overbeek (DLVO) theory and the soft-sphere model, respectively. Specifically, the model was used to study the effects of pH, solid volume fraction and external AC electric field on α-alumina aggregate growth which was expressed in terms of coordination number, longest dimension, and fractal dimension. The simulations were carried out over a pH range of 4-10, solid volume fraction of 0.02-0.4, and a variety of AC electric fields. In relatively dilute suspensions, the aggregates predominantly exhibited chainlike structures, whereas at high solid volume fraction, aggregates with complex netlike structures were formed. It was also evident that, in concentrated colloidal suspensions, DEP had a negligible influence on aggregate growth over the examined conditions. The effect of DEP however, was found to be more noticeable on aggregate structure leading to the formation of more compact aggregates with a greater particle number density. The break-up and reattachment of sub-aggregates as well as the rearrangement of nanoparticles in the particle assemblies and subsequent curling of the loose network promoted by a strong AC electric field was deemed to be responsible for this structural transformation. Finally, the DEM-based model was used to predict the size of α-alumina aggregates over a range of pH. The predictions were found to be in good agreement with the published experimental data, particularly around the isoelectric point.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="1f54f41443c1e2d05475c110a8454871" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":95602229,"asset_id":92650137,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/95602229/download_file?st=MTczMzkyMDA3Myw4LjIyMi4yMDguMTQ2&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="92650137"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="92650137"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 92650137; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=92650137]").text(description); $(".js-view-count[data-work-id=92650137]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 92650137; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='92650137']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 92650137, container: "", }); });</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-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "1f54f41443c1e2d05475c110a8454871" } } $('.js-work-strip[data-work-id=92650137]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":92650137,"title":"DEM simulation of aggregation of suspended nanoparticles","translated_title":"","metadata":{"publisher":"Elsevier BV","grobid_abstract":"A DEM-based model was developed and examined for simulation of aggregation in suspensions of α-alumina nanoparticles.

Aggregate surface area was directly determined by aggregate structural characteristics, and increased rapidly when the coordination number was below 3.5 and the fractal dimension was less than 1.5.

A correlation for prediction of aggregate external surface area was also proposed as a function of aggregate structural characteristics in terms of fractal dimension and coordination number.","owner":{"id":132470,"first_name":"Geoffrey","middle_initials":null,"last_name":"Evans","page_name":"GeoffreyEvans","domain_name":"newcastle-au","created_at":"2010-02-14T19:05:27.687-08:00","display_name":"Geoffrey Evans","url":"https://newcastle-au.academia.edu/GeoffreyEvans"},"attachments":[{"id":95602181,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/95602181/thumbnails/1.jpg","file_name":"28938.pdf","download_url":"https://www.academia.edu/attachments/95602181/download_file?st=MTczMzkyMDA3Myw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"A_method_for_calculating_the_surface_are.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/95602181/28938-libre.pdf?1670801645=\u0026response-content-disposition=attachment%3B+filename%3DA_method_for_calculating_the_surface_are.pdf\u0026Expires=1733923673\u0026Signature=C3L9PuvhkqbpC2A8Xo1zgaSLwuQQ0MJ13Dmlws7HgE7w~cBFrheAC1Rc4HnoWABeYjphnXU9TYsLWXzprgbZvKif6foixorqx27GDOSmQNF12wpOYglxtOkVern366AHJ52II6jZPacus7mlGsEkl8F31Puc8-qyzHmcCnj0ikxY8cjbjaC-hfZOUv~E0u64eDspCuo2dH9AUuc~HjW-34OIgjPIz1Qzr8q9wMqaf41oh-8Yq5mLTDE0XjhslGCq4GcZVKS4nj-Tf1dIWzi6NcEDe~AHW4RgpGuH55b-Jb~NsSYUTPk2nKGjaUlLvPXoz9pEvEHOYGuYJJ8fKCvuoA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering"},{"id":72,"name":"Chemical Engineering","url":"https://www.academia.edu/Documents/in/Chemical_Engineering"},{"id":511,"name":"Materials Science","url":"https://www.academia.edu/Documents/in/Materials_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":1139,"name":"Publishing","url":"https://www.academia.edu/Documents/in/Publishing"},{"id":60658,"name":"Numerical Simulation","url":"https://www.academia.edu/Documents/in/Numerical_Simulation"},{"id":90962,"name":"Academic research","url":"https://www.academia.edu/Documents/in/Academic_research"},{"id":132495,"name":"Commissioning","url":"https://www.academia.edu/Documents/in/Commissioning"},{"id":216442,"name":"Specific surface area","url":"https://www.academia.edu/Documents/in/Specific_surface_area"},{"id":390245,"name":"Particle Size","url":"https://www.academia.edu/Documents/in/Particle_Size"},{"id":721120,"name":"Coordination number","url":"https://www.academia.edu/Documents/in/Coordination_number"},{"id":890611,"name":"Fractal Dimension","url":"https://www.academia.edu/Documents/in/Fractal_Dimension"},{"id":1277758,"name":"Structural Characteristics","url":"https://www.academia.edu/Documents/in/Structural_Characteristics"}],"urls":[]}, 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="92650132"><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/92650132/Stability_analysis_in_solid_liquid_fluidized_beds_Experimental_and_computational"><img alt="Research paper thumbnail of Stability analysis in solid–liquid fluidized beds: Experimental and computational" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.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/92650132/Stability_analysis_in_solid_liquid_fluidized_beds_Experimental_and_computational">Stability analysis in solid–liquid fluidized beds: Experimental and computational</a></div><div class="wp-workCard_item"><span>Chemical Engineering Journal</span><span>, 2014</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">ABSTRACT In this study the transition from homogeneous to heterogeneous flow in a solid–liquid fl...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">ABSTRACT In this study the transition from homogeneous to heterogeneous flow in a solid–liquid fluidized bed (SLFB) is examined both experimentally and numerically. The experimental apparatus comprised a refractive index-matched SLFB, comprising 5 mm diameter borosilicate glass and sodium iodine solution, which allowed for both instantaneous particle image velocimetry of the liquid flow field and solids hold-up measurements to be undertaken for superficial liquid velocities in the range of 0.06–0.22 m/s. The motion of individual, spherical steel balls (with diameters 6, 7, 8, 9 mm) was then tracked as it settled through the fluidized bed for differing superficial liquid velocities. It was observed that, for all the steel balls covered in this work, there was a change in slope in their respective classification velocity curves at a superficial liquid velocity of 0.08 m/s. This value was very close to the critical velocity of 0.085 m/s predicted from 1-D linear stability analysis; and therefore deemed to be the critical condition that marked the transition from homogeneous to non-homogenous flow. It is proposed that the change in slope of the classification velocity curve is due to the encounter of the settling foreign particles with liquid bubbles whose presence marks the onset of heterogeneous flow. Additional computational analysis, involving both Eulerian–Eulerian (E–E) and Eulerian–Lagrangian (E–L) approaches, is used to confirm the presence of liquid bubbles at a critical liquid hold-up of 0.54, which corresponds to that predicted from 1-D linear stability analysis. In summary, the study has highlighted that experimentally the transition condition for a SLFB can be obtained simply by observing the behavior of the classification velocity of a single foreign particle at different superficial liquid velocities. This transition condition was found to agree with the 1D linear stability criterion, Eulerian–Eulerian CFD (3D) and Eulerian–Lagrangian DEM (3D) approaches.</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="92650132"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="92650132"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 92650132; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=92650132]").text(description); $(".js-view-count[data-work-id=92650132]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 92650132; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='92650132']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 92650132, container: "", }); });</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-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.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" } } $('.js-work-strip[data-work-id=92650132]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":92650132,"title":"Stability analysis in solid–liquid fluidized beds: Experimental and computational","translated_title":"","metadata":{"abstract":"ABSTRACT In this study the transition from homogeneous to heterogeneous flow in a solid–liquid fluidized bed (SLFB) is examined both experimentally and numerically.

The knowledge of hydrodynamics of packed and fluidised beds in capillary tubes is essential for the design and optimization of such devices. This study experimentally examines the hydrodynamics of packed and fluidised beds in terms of pressure drop, bed expansion and minimum fluidisation velocity in tube sizes with inner diameters of 0.8, 1.2 and 17.1mm. Specifically the influence of the wall on the hydrodynamic characteristics of the beds was examined by changing the tube-to-particle diameter ratio.It was found that as the tube diameter reduces the bed voidage sharply increases leading to a reduction in the pressure drop across the bed. Also a pressure drop overshoot was observed at lower tube-to-particle diameter ratios which found to be associated with contact stresses due to wall friction.</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="92650129"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="92650129"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 92650129; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=92650129]").text(description); $(".js-view-count[data-work-id=92650129]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 92650129; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='92650129']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 92650129, container: "", }); });</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-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.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" } } $('.js-work-strip[data-work-id=92650129]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":92650129,"title":"Fluidisation and packed bed behaviour in capillary tubes","translated_title":"","metadata":{"abstract":"ABSTRACT Packed and fluidised beds in microfluidic devices offer the potential of enhanced heat and mass transfer capability at a scale where the process can be closely controlled.

Three different combinations of particle size pairs of both equal and unequal mass ratios were used using a constant liquid (water) superficial velocity of 0.17 ms in all the cases. Numerically, a two dimensional Eulerian-Eulerian (E-E) CFD model incorporating kinetic theory of granular flow (KTGF) was developed to predict the bed expansion behaviour. It was observed that complete bed segregation occurred when the difference between the solid particle diameters was higher while lower difference in particle diameters led to partial bed segregation.

The research hubs are part of a new initiative aimed at building stronger relationships between industry and universities, while addressing issues of national significance. "The ARC Research Hub for Advanced Technologies for Australian Iron Ore" will focus its attention on developing innovative approaches for creating enhanced value across the full value chain, through characterisation of different ore types, beneficiation, and materials handling and transport. This hub brings together five industrial organisations and a research team formed from well-established research groups based at the Newcastle Institute for Energy and Resources (NIER). These groups have a record of working closely with industry, creating opportunities.

Depending on the impact Weber number (1.4-23.9) of the particles either complete capture of the particle inside the film or complete penetration through the film were observed. In the latter case a certain amount of liquid mass was found to adhere to the particle surface which again depended on the impact Weber number.

However, the motion of a floating marble has yet to be systematically characterised due to the lack of insight into key parameters such as the coefficient of friction between the floating marble and the carrier liquid. We measured the coefficient of friction of a small floating marble using a novel experimental setup that exploits the non-wetting properties of a liquid marble. A floating liquid marble pair containing a minute amount magnetite particles were immobilised and then released in a controlled manner using permanent magnets. The capillarity-driven motion was analysed to determine the coefficient of friction of the liquid marbles. The "capillary charge" model was used to fit the experimental results.

A floating marble can easily move across water surface due to the low friction, allowing for the transport of aqueous solutions with minimal energy input. However, the motion of a floating marble has yet to be systematically characterised due to the lack of insight into key parameters such as the coefficient of friction between the floating marble and the carrier liquid. We measured the coefficient of friction of a small floating marble using a novel experimental setup that exploits the non-wetting properties of a liquid marble. A floating liquid marble pair containing a minute amount magnetite particles were immobilised and then released in a controlled manner using permanent magnets. The capillarity-driven motion was analysed to determine the coefficient of friction of the liquid marbles. The \"capillary charge\" model was used to fit the experimental results.

The lack of gravimetric measurement limits further understanding on the physical changes of a liquid marble during the evaporation process. Furthermore, the evaporation process of a marble containing a liquid binary mixture has not been reported. This paper studies the effective density and effective surface tension of an evaporating liquid marble which contains aqueous ethanol at relatively low concentrations. The effective density of an evaporating liquid marble is determined from the instantaneous mass and volume measurements. Subsequently, density measurements combined with surface profile fitting provides the instantaneous effective surface tension of the marble. We found that the density and surface tension of the evaporating marble is greatly affected by the particle coating.","owner":{"id":132470,"first_name":"Geoffrey","middle_initials":null,"last_name":"Evans","page_name":"GeoffreyEvans","domain_name":"newcastle-au","created_at":"2010-02-14T19:05:27.687-08:00","display_name":"Geoffrey Evans","url":"https://newcastle-au.academia.edu/GeoffreyEvans"},"attachments":[{"id":95602182,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/95602182/thumbnails/1.jpg","file_name":"PUB3086.pdf","download_url":"https://www.academia.edu/attachments/95602182/download_file?st=MTczMzkyMDA3Myw4LjIyMi4yMDguMTQ2&st=MTczMzkyMDA3Myw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Evaporation_of_ethanol_water_binary_mixt.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/95602182/PUB3086-libre.pdf?1670801649=\u0026response-content-disposition=attachment%3B+filename%3DEvaporation_of_ethanol_water_binary_mixt.pdf\u0026Expires=1733923673\u0026Signature=IQbKMLHpyLFBtJXzIH9Z~5xYWTVDKiMALOe4nN-iP5UAh3pAi7AYngqL49UtwvlW9sBAuf5yU3XhXsKfDQh9zCfLetXpEhlWIr7SFN9aYCBz9faeGQd6GYYe~y3p2znpiHKwVyPfBzldCBaBep97Ve9t-msRdzdFr7VgcaCRb2nZkoRyQXBMpNcMhy2siyI2SPbCCmVZK8u2jSOhnqJhkcsIf55mFBk8HuwdKfg4y~sJb1FeFjwUyH8L76MZaX2X7Pee3jh5NKOZHKXTmjmnzT~7DuJU1qPMeRCJlx8RF311dO6Bo-br850KuLc1FpClzvuw6m-HqVkx1BmxMzI~Rg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":505,"name":"Condensed Matter Physics","url":"https://www.academia.edu/Documents/in/Condensed_Matter_Physics"},{"id":511,"name":"Materials Science","url":"https://www.academia.edu/Documents/in/Materials_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":2166,"name":"Surfaces and Interfaces","url":"https://www.academia.edu/Documents/in/Surfaces_and_Interfaces"},{"id":4748,"name":"Electrochemistry","url":"https://www.academia.edu/Documents/in/Electrochemistry"},{"id":5427,"name":"Spectroscopy","url":"https://www.academia.edu/Documents/in/Spectroscopy"},{"id":13268,"name":"Evaporation","url":"https://www.academia.edu/Documents/in/Evaporation"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary"},{"id":211877,"name":"Wetting","url":"https://www.academia.edu/Documents/in/Wetting"},{"id":394521,"name":"Surface Tension","url":"https://www.academia.edu/Documents/in/Surface_Tension"},{"id":743666,"name":"Langmuir","url":"https://www.academia.edu/Documents/in/Langmuir"},{"id":1246521,"name":"Liquid Marble","url":"https://www.academia.edu/Documents/in/Liquid_Marble"},{"id":1664651,"name":"Gravimetric Analysis","url":"https://www.academia.edu/Documents/in/Gravimetric_Analysis"}],"urls":[]}, 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="92650138"><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/92650138/Interaction_dynamics_of_a_spherical_particle_with_a_suspended_liquid_film"><img alt="Research paper thumbnail of Interaction dynamics of a spherical particle with a suspended liquid film" class="work-thumbnail" src="https://attachments.academia-assets.com/95602183/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/92650138/Interaction_dynamics_of_a_spherical_particle_with_a_suspended_liquid_film">Interaction dynamics of a spherical particle with a suspended liquid film</a></div><div class="wp-workCard_item"><span>AIChE Journal</span><span>, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">in Wiley Online Library (wileyonlinelibrary.com) Hydrodynamics of collision interactions between ...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">in Wiley Online Library (wileyonlinelibrary.com) Hydrodynamics of collision interactions between a particle and gas-liquid interface such as droplet/film is of keen interest in many engineering applications.

In the model, the random Brownian diffusion and the externally induced dielectrophoresis (DEP) motion were considered as the driving mechanisms for the transport of particles in colloidal suspension. To simulate particle interactions, the non-contact surface force and the contact force were taken into account using the well-known Derjaguin-Landau-Verway-Overbeek (DLVO) theory and the soft-sphere model, respectively. Specifically, the model was used to study the effects of pH, solid volume fraction and external AC electric field on α-alumina aggregate growth which was expressed in terms of coordination number, longest dimension, and fractal dimension. The simulations were carried out over a pH range of 4-10, solid volume fraction of 0.02-0.4, and a variety of AC electric fields. In relatively dilute suspensions, the aggregates predominantly exhibited chainlike structures, whereas at high solid volume fraction, aggregates with complex netlike structures were formed. It was also evident that, in concentrated colloidal suspensions, DEP had a negligible influence on aggregate growth over the examined conditions. The effect of DEP however, was found to be more noticeable on aggregate structure leading to the formation of more compact aggregates with a greater particle number density.

The physical processing of these multiphase systems is carried out at all scales of operation and within an endless variety of vessel shapes and ancillary devices. Underpinning each process is a complex interaction between phases involving hydrodynamic, heat and mass transport. These phenomena are in turn governed largely by the nature of the flow, and in particular whether laminar or turbulent conditions prevail.

The experimental apparatus comprised a refractive index-matched SLFB, comprising 5 mm diameter borosilicate glass and sodium iodine solution, which allowed for both instantaneous particle image velocimetry of the liquid flow field and solids hold-up measurements to be undertaken for superficial liquid velocities in the range of 0.06–0.22 m/s. The motion of individual, spherical steel balls (with diameters 6, 7, 8, 9 mm) was then tracked as it settled through the fluidized bed for differing superficial liquid velocities. It was observed that, for all the steel balls covered in this work, there was a change in slope in their respective classification velocity curves at a superficial liquid velocity of 0.08 m/s. This value was very close to the critical velocity of 0.085 m/s predicted from 1-D linear stability analysis; and therefore deemed to be the critical condition that marked the transition from homogeneous to non-homogenous flow. It is proposed that the change in slope of the classification velocity curve is due to the encounter of the settling foreign particles with liquid bubbles whose presence marks the onset of heterogeneous flow. Additional computational analysis, involving both Eulerian–Eulerian (E–E) and Eulerian–Lagrangian (E–L) approaches, is used to confirm the presence of liquid bubbles at a critical liquid hold-up of 0.54, which corresponds to that predicted from 1-D linear stability analysis. In summary, the study has highlighted that experimentally the transition condition for a SLFB can be obtained simply by observing the behavior of the classification velocity of a single foreign particle at different superficial liquid velocities. This transition condition was found to agree with the 1D linear stability criterion, Eulerian–Eulerian CFD (3D) and Eulerian–Lagrangian DEM (3D) approaches.</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="92650132"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="92650132"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 92650132; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=92650132]").text(description); $(".js-view-count[data-work-id=92650132]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 92650132; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='92650132']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 92650132, container: "", }); });</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-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.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" } } $('.js-work-strip[data-work-id=92650132]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":92650132,"title":"Stability analysis in solid–liquid fluidized beds: Experimental and computational","translated_title":"","metadata":{"abstract":"ABSTRACT In this study the transition from homogeneous to heterogeneous flow in a solid–liquid fluidized bed (SLFB) is examined both experimentally and numerically.

The discrete element model (DEM) combined with the well-known DLVO theory was employed to obtain an insight into the aggregation process of nanoparticles with different PPSDs, where a modified version of the Flatt and Brown model [J. Am. Ceram. Soc. 89 (2006) 1244-1256] [9] was employed to calculate the corresponding suspension yield stress from the simulation results. Specifically, the aggregate growth and structure in terms of fractal dimension, coordination number and the longest dimension were examined. It was shown that at small PPSD variances, a netlike structure was formed with aggregate branches interconnected in multiple locations, whereas at large variances aggregates with more compact structure and smaller longest dimension were generated. The rate of aggregation and particle assemblage was found to be faster at broader PPSDs, in turn generating aggregates with narrower size distributions and more compact structures.
