摘要
采用CFD和CAA方法对可逆转轴流风机进行三维流场和声场数值模拟,分析了3种叶片翼型对风机性能和噪声的影响,根据数值模拟结果及分析得出结论。
In this paper, 3-D numerical simulation is carried out on reversible axial-flow fan to predict flow field and sound field using CFD and CAA technology in order to analyze the effects of three types of airfoil on the performance and noise of the fan.A conclusion will be gained according to the result and analysis of the numerical simulation.
