Computational Study of the Combined Effects of Conduction-Radiation and Hydromagnetic on Natural Convection Flow Past a Magnetized Permeable Plate

  • 摘要: 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.
