In this paper, turbulent flow inside the centrifugal blower has been studied numerically. The computational simulation is conducted by employing the Reynolds Averaged NavierStokes (RANS) approach. The standard k-ɛ model with enhanced wall treatment has been implemented for modeling the turbulent flow. Effects of different angular velocities have been studied on static pressure and mass flow rate. The numerical results shows that static pressure and mass flow rate significantly increase as the angular velocity of blades increases.
