Technical Institute of Physics and Chemistry, Chinese Academy of Sciences Beijing 100190; 2. University of Chinese Academy of Sciences Beijing 100190; 3. Technical Research Lab.CEDIC Co. Ltd. Seoul Korea) Abstract：Fans are widely applied in home appliances such as refrigerator, air conditioner, et al, whose performance, especially noise level, is one of the main factors that determines the whole products. in order to improve the optimal design of fans, it is presented the design process assisted by computer simulation by integrated the flow fluid simulation and noise source and flow noise simulation. The flow field can be calculated with 3-dimensional CFD solver, and the noise source and flow noise is calculated with Ffowcs- Williams and Hawkings equations. This method and software are applied to analyze the flow field and flow noise of the axial fan, cross flow fan and centrifugal fan in home appliances, and the simulation results agree well with the experimental data. These results show t
