摘要

考虑了定向磁场、交叉扩散和辐射效应下垂直拉伸表面上的二维稳定流动。利用相似变换将控制偏微分方程转化为非线性常微分方程,然后利用MATLAB包中的bvp4c进行数值求解。讨论了各种无量纲控制参数对速度、温度、浓度沿摩擦系数、努塞尔数和舍伍德数分布的影响,并以图表的形式给出了这些影响。我们观察到,排列角的增加会增强磁场,降低流动的速度分布,提高换热率。并与已有结果进行了比较。

Radiation, inclined magnetic field and cross-diffusion effects on flow over a stretching surface

The steady two-dimensional flow over a vertical stretching surface in presence of aligned magnetic field, cross-diffusion and radiation effects are considered. The governing partial differential equations are transformed to nonlinear ordinary differential equation by using similarity transformation and then solved numerically by using bvp4c with MATLAB package. The effects of various non-dimensional governing parameters on velocity, temperature, concentration profiles along friction factor, Nusselt and Sherwood numbers are discussed and presented through graphs and tables’.We observed that increase in aligned angle strengthen the magnetic field and decreases the velocity profile of the flow and enhances the heat transfer rate. Comparisons with existed results are presented.
