摘要
以OB-100型轴流通风机为研究对象,基于SIMPLE算法对三维椭圆形N-S方程和k-ε紊流模型进行数值计算,得到了叶轮径向流面和轴向流面的动力学特征并进行了分析,总结了两类特征流面压力分布的规律。
In this paper, set the OB- 100 type axial-flow fan as the research object, the dynamics characteristics of radial and axial flow surface of impeller are obtained and analyzed based on the numerical calculation of SIMPLE algorithm to 3- D elliptical N- S equation and κ- ε turbulence model. The pressure distribution rules of two characteristics flow surfaces have been summarized.
