Article Preview

This paper presents a modification to the existing blade force model of Wu et al. [5] to predict noise radiated from a low-pressure axial flow fan. The aerodynamic theory for the fan impeller is introduced and the module analysis is conducted to calculate the flow parameters more accurately, the lift coefficient is modified by taking into account the specific shape of the blade, and an empirical parameter is also replaced by the CFD simulation based on FLUENT software. The numerical prediction on the noise radiated from the fan is performed by using the modified model, and the predicted results are more closely to the experimental results than those before modification.
