研究粘性、不可压缩、导电流体,在磁化可渗透竖直平板上作自然对流时,数值地分析辐射和磁流体组合的影响.采用两种方法数值地求解非相似的控制方程:1)对所有吸入参数值ξ,采用有限差分法;2)为小数值和大数值的吸入参数值ξ,分别建立起级数的渐近解.用图形和列表形式,给出Prandtl数Pr,磁Prandtl数Pm,磁力参数S,辐射参数Rd,壁面温度θw的变化,对壁面摩擦因数、热交换率和电流密度的影响.最后分析上述物理参数对速度分布、温度分布和磁场横向分量的影响.
The viscous, incompressible, conductive fluids are studied numerically for the effects of radiative and magnetic fluid combinations when they are spontaneous convection on a magnetizable vertical plate.The two methods are used to numerically solve the dissimilar control equations: 1) For all Inhalation of the parameter ξ, using the finite difference method; 2) Asymptotic solution of the series number for the inhalation parameter value ξ of the decimal value and the large value, respectively. With the form of the graph and the list, the Prandtl number Pr, the magnetic Prandtl number Pm , The influence of the magnetic parameters S, the radiation parameters Rd and the wall temperature θw on the friction coefficient, the heat exchange rate and the current density were discussed.Finally, the effects of the above physical parameters on the velocity distribution, temperature distribution and transverse magnetic field components were analyzed.
