Abstract

In this paper, a 3d flow field of multi-blade centrifugal fan is simulated with Fluent. The influence of typical geometric parameters on fan´s flow rate and noise is studied. Coupled algorithm, MUSCL discretization scheme and steady RANS equations are used to solve the internal flow field of the fan. FW-H acoustic model incorporated with the large eddy simulation is used to calculate flow noise of the fan. The results indicate that calculation data under different operating conditions coincide with the experimental results. Fan tongue radius, number of blades and blade´s import settling angle have significant influences on flow rate and flow noise. The results provide a reference to the optimal design of multi-blade centrifugal fan.
