研究了源/汇作用下微极流体的MHD边界层流动和可渗透收缩片上的换热问题。用相似变换将高度非线性的运动偏微分方程转化为常微分方程。然后使用逐次超松弛（SOR）方法和辛普森（1/3）规则对所得方程进行数值求解。Richardson外推法改进了数值计算结果。考察了哈特曼数M、质量吸力参数S、普朗特数Pr和热源/热源参数对速度、微旋转和温度分布特征的影响。讨论了微极流体与牛顿流体结果的比较。
MHD boundary layer flow of micropolar fluids and heat transfer over a permeable shrinking sheet under the effects of heat source/ sink is studied. Similarity transformations have been used to transform the highly nonlinear partial differential equations of motion in to ordinary differential form. The resulting equations are then solved numerically using Successive over Relaxation (SOR) method and Simpson’s (1/3) rule. The numerical results are improved by Richardson’s extrapolation. The effects of various parameters namely, Hartmann number M , mass suction parameter S, Prandtl number Pr and heat source / sink parameter are observed on the features of the velocity, microrotation and temperature profiles. Comparison of the results of micropolar fluids with Newtonian fluids is discussed.
