转、静盘腔径向出口流场与换热研究

Investigation of the Radial Exit Flow Field and Heat Transfer in Space between the Rotating and Stationary Discs

采用SIMPLE算法对具有中心入射流的开式转静盘腔中的流动与换热进行了计算研究。计算了流场中 3D速度分量、温度场 ,得出了转静盘系层流流动的规律 ,分析了流场中出现旋涡的变化规律。

The flow field and heat Transfer in space between the rotating and stationary d iscs are described. The three dimensional velocity and temperature in the flow field are computed with the SIMPLE algorithm. The variations of vortex and exit velocity are analyzed. The effect of diffusion and convection terms on the temperature field is disc ussed.
