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.
At present, with the exception of CFD (computational fluid dynamics) simulation where CAA (computational aerodynamic acoustics) is involved, the main noise prediction model of the fan can be grouped into two categories: (1) the wake shedding model represented by Fukano et al. [1] and Lee et al. [2], whose main idea is to describe the turbulent noise of the shedding vortex at the trailing edge of the blade of the fan using a simple physical model taking the wake width as the main parameter.
Huang [5] devoted the model of Lowson [3] to the simulation of a computer cooling fan, and achieved good results.
