- 瑞利数RaRa
- 给出了以流函数表示的无量纲基本方程，用控制容积法对方程离散并进行了数值计算，得到了多孔介质内的流场、温度场和浓度场，讨论了瑞利数Ra和刘易斯数Le对多孔介质传热传质的影响。The dimensionless equations are obtained by introducing stream function, using the control volume formulation. And the natural convection in a porous medium has been studied by numerical calculation including the flow field, temperature and concentration profiles. The effects of Rayleigh number Ra and Lewis number Le on heat and mass transfer of a porous medium have also been numerically studied.
