摘要

本文研究了粘性不可压缩流体在具有多孔边界的倾斜磁场作用下通过矩形管道的二维稳态MHD流动。采用有限差分法将耦合的偏微分方程转化为代数方程组，并在Matlab软件中编程，同时采用高斯沉降迭代法求解。在吸/注参数()、哈特曼数()和倾角()的不同量纲参数值下，得到了速度线、感应磁场线和电流密度线的数值解，并进行了分析，并以图形形式给出。MSC 2010: 76d05, 76w05, 76m20

Effects of the porous boundary and inclined magnetic field on MHD flow in a rectangular duct

In this work, a steady two dimensional MHD flow of a viscous incompressible fluid through a rectangular duct under the action of an inclined magnetic field with a porous boundary has been investigated. The coupled partial differential equations are transformed into a system of algebraic equations using the finite difference method and are then solved simultaneously using the Gauss Seidal iteration method by programming in Matlab software. Numerical solutions for velocity, induced magnetic field and current density lines are obtained and analyzed for different values of dimensionless parameters namely suction/ /injection parameter ( ), Hartmann number ( ) and inclination angle ( ) and are presented graphically.
