The diffusers are essential for effective transformation of the kinetic power produced by the rotor in a centrifugal fan. Hence the flow in the impeller and diffuser passages is the important phenomenon in optimizing the performance. These impeller and diffuser flow passages are the most complex regions to predict the flow behavior. With the advanced development of Particle Image Velocimetry as well as convenient numerical CFD tools, it has become possible to reach at an accurate result well-matched with the real behavior of the flow. Hence, in this work moving mesh technique is used to get a numerical solution for the estimation of actual flow manner. Numerous research works have been done recently to get the physics of fluid flow through impeller and diffuser, both numerically and experimentally. But it is found from the literature that the study on the performance of the fan by changing the number of impeller and diffuser blades together in a combination has not been the emphasis of attention in these works. Hence a numerical analysis has been carried out in this paper to comprehensively lookout the fluid interaction in impeller-diffuser as well as to envisage the flow behavior of the fan by changing the number of impeller and diffuser blades together in combination. For the same number of impeller blades, it is found from the analysis that a higher static pressure rise coefficient is achieved at the outlet of the fan for smaller number of diffuser blades. It is also found that larger the number of impeller blades, larger is the static pressure rise coefficient for the same number of diffuser blades, hence performance gets improved.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"INFLUENCE OF NUMBER OF IMPELLER AND DIFFUSER BLADES ON THE PRESSURE RECOVERY OF CENTRIFUGAL FAN","attachmentId":42357780,"attachmentType":"pdf","work_url":"https://www.academia.edu/21674429/INFLUENCE_OF_NUMBER_OF_IMPELLER_AND_DIFFUSER_BLADES_ON_THE_PRESSURE_RECOVERY_OF_CENTRIFUGAL_FAN","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/21674429/INFLUENCE_OF_NUMBER_OF_IMPELLER_AND_DIFFUSER_BLADES_ON_THE_PRESSURE_RECOVERY_OF_CENTRIFUGAL_FAN"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="64624350" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/64624350/Effects_of_inlet_conditions_on_centrifugal_diffuser_performance">Effects of inlet conditions on centrifugal diffuser performance</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="44243062" href="https://independent.academia.edu/DenizSabri">Sabri Deniz</a></div><p class="ds-related-work--metadata ds2-5-body-xs">1997</p><p class="ds-related-work--abstract ds2-5-body-sm">This report examines the influence of inlet flow conditions, including Mach number, flow angle, blockage, and axial flow non-uniformity, on the performance and operating range of a straight channel centrifugal compressor diffuser. The research was carried out in a unique facility specifically developed to provide the diffuser with a controlled inlet flow. The tests were carried out for inlet Mach number up to values greater than unity and for a range of inlet flow angles up to the onset of rotating stall. It was found that expressing the overall diffuser pressure recovery coefficient, defined using availability or mass averaged inlet total pressure, as a function of momentum averaged diffuser inlet flow angle yields a relationship which is essentially independent of diffuser inlet flow distortion, blockage, or Mach number. Further, the operating range of the diffuser was limited by the onset of rotating stall at a momentum averaged diffuser inlet flow angle (oc = 70.5 0.5), which wa...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Effects of inlet conditions on centrifugal diffuser performance","attachmentId":76573861,"attachmentType":"pdf","work_url":"https://www.academia.edu/64624350/Effects_of_inlet_conditions_on_centrifugal_diffuser_performance","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/64624350/Effects_of_inlet_conditions_on_centrifugal_diffuser_performance"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="2" data-entity-id="69055520" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/69055520/Overall_Performance_of_a_Centrifugal_Vaned_Diffuser_Pump_for_Different_Flow_Rates_Experimental_and_Numerical_Comparisons">Overall Performance of a Centrifugal Vaned Diffuser Pump for Different Flow Rates, Experimental and Numerical Comparisons</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="107238587" href="https://independent.academia.edu/HBouchelkia">Hamid Bouchelkia</a></div><p class="ds-related-work--metadata ds2-5-body-xs">WSEAS TRANSACTIONS ON FLUID MECHANICS</p><p class="ds-related-work--abstract ds2-5-body-sm">The article presents the analysis of the interactions between the impeller and the vaned diffuser of a radial flow pump.

The paper describes tests of straight-channel type diffuser, sometimes called a wedge-vane diffuser, and compares the results with those from the discrete-passage diffusers described in Part 1. Effects of diffuser inlet Mach number, flow angle, blockage, and axial flow non-uniformity on diffuser pressure recovery and operating range are addressed. The straight-channel diffuser investigated has 30 vanes and was designed for the same aerodynamic duty as the discrete-passage diffuser described in Part 1. The ranges of the overall pressure recovery coefficients were 0.65-0.78 for the straight-channel diffuser and 0.60-0.70 for the discrete-passage diffuser; the pressure recovery of the straight-channel diffuser was roughly 10% higher than that of the discrete-passage diffuser. Both types of the diffusers showed similar behavior regarding the dependence on diffuser inlet flow angle and the insensitivity of the performance to inlet flow field axial distortion and Mach number. The operating range of the straight-channel diffuser, as for the discrete-passage diffusers was limited by the onset of rotating stall at a fixed momentum-averaged flow angle into the diffuser, which was for the straight-channel diffuser, atit = 70° ±0.5°. The background, nomenclature and description of the facility and method are all given in Part 1.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Effects of Inlet Flow Field Conditions on the Performance of Centrifugal Compressor Diffusers: Part 2 — Straight-Channel Diffuser","attachmentId":107912007,"attachmentType":"pdf","work_url":"https://www.academia.edu/109939032/Effects_of_Inlet_Flow_Field_Conditions_on_the_Performance_of_Centrifugal_Compressor_Diffusers_Part_2_Straight_Channel_Diffuser","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/109939032/Effects_of_Inlet_Flow_Field_Conditions_on_the_Performance_of_Centrifugal_Compressor_Diffusers_Part_2_Straight_Channel_Diffuser"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="5" data-entity-id="47989779" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/47989779/A_Study_of_Impeller_Diffuser_Volute_Interaction_in_a_Centrifugal_Fan">A Study of Impeller-Diffuser-Volute Interaction in a Centrifugal Fan</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="109441341" href="https://independent.academia.edu/tarekMeakhail">tarek Meakhail</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Turbomachinery, 2005</p><p class="ds-related-work--abstract ds2-5-body-sm">This paper reports velocity measurement data in the interaction region between the impeller and vaned diffuser and the results of numerical flow simulation of the whole machine (impeller, vaned diffuser and volute) of a single stage centrifugal fan. Two-dimensional instantaneous velocity measurement is done using particle image velocimetry (PIV). Numerical simulation of impeller-diffuser-volute interaction is performed using CFX-Tascflow commercial code. A frozen rotor simulation model is used for the steady calculation and a rotor-stator simulation model is used for the unsteady calculation using the steady results as an initial guess. The simulation results show that the separated flow regime near the diffuser hub extends to the volute. Comparison between the unsteady computation and those of measurement indicates that the rotor/stator model employed in the simulation predicts essential characteristics of unsteady flow in the centrifugal fan. However, quantitative agreement remain...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Study of Impeller-Diffuser-Volute Interaction in a Centrifugal Fan","attachmentId":66834765,"attachmentType":"pdf","work_url":"https://www.academia.edu/47989779/A_Study_of_Impeller_Diffuser_Volute_Interaction_in_a_Centrifugal_Fan","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/47989779/A_Study_of_Impeller_Diffuser_Volute_Interaction_in_a_Centrifugal_Fan"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="95807838" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/95807838/Numerical_Investigation_of_Radial_Fan_with_Forward_Curved_Blades">Numerical Investigation of Radial Fan with Forward Curved Blades</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="255058479" href="https://independent.academia.edu/ThesisFinal">Final Thesis</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2013</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Numerical Investigation of Radial Fan with Forward Curved Blades","attachmentId":97886625,"attachmentType":"pdf","work_url":"https://www.academia.edu/95807838/Numerical_Investigation_of_Radial_Fan_with_Forward_Curved_Blades","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/95807838/Numerical_Investigation_of_Radial_Fan_with_Forward_Curved_Blades"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="109939029" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/109939029/Effects_of_Inlet_Flow_Field_Conditions_on_the_Performance_of_Centrifugal_Compressor_Diffusers_Part_1_Discrete_Passage_Diffuser">Effects of Inlet Flow Field Conditions on the Performance of Centrifugal Compressor Diffusers: Part 1 — Discrete-Passage Diffuser</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="44243062" href="https://independent.academia.edu/DenizSabri">Sabri Deniz</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Volume 1: Turbomachinery, 1998</p><p class="ds-related-work--abstract ds2-5-body-sm">This is Part 1 of a two-part paper considering the performance of radial diffusers for use in a high performance centrifugal compressor.
