Abstract:
A 3D forward curved (FC) centrifugal fan with airfoil blades is simulated numerically to predict the turbulent flow and pressure field of the fan. Through this numerical simulation, the influence of blade number on the fan performance is surveyed. In numerical analysis, finite volume method (FVM) is used to solve the governing equations. The numerical results are validated with experimental data. It is observed that the 20 is the most efficient blade number for this type offan. Also least square method is used to optimize the blade number. This optimization predicts 21 blade number as the most efficient one.
