- 給出了以流函數表示的無量綱基本方程，用控制容積法對方程離散並進行了數值計算，得到了多孔介質內的流場、溫度場和濃度場，討論了瑞利數Ra和劉易斯數Le對多孔介質傳熱傳質的影響。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.
