COMPUTATIONAL FLUID DYNAMICS SIMULATION OF PROPELLER FAN

Cooling appliance s growing demand to cool the ambience with high efficiency requires robust condenser unit. The objective of this work is to predict and correlate the mass flow rate of propeller type axial fan used in condenser unit using Computational Fluid Dynamics (CFD) technique. The flow field is simulated with the finite ele ment Computational Fluid Dynamics CFD solver Altair HyperWorks. The three - dimensional computational domain with Spalart - Allmaras turbulence model is considered to predict the mass flow rate. The present computation is carried out for the axial fan speed of 820 rpm for the steady state condition using moving reference frame approach. The flow rate is correlated with the test results to validate the CFD modeling approach. The correlation level found closer with tested results, hence which will help to improve the futuristic model during conceptual design itself.
