Abstract

The paper analyzes steady laminar boundary layer flow of low-conductivity Casson fluid over a stretching/shrinking sheet subjected to a transverse magnetic field in the presence of suction/injection when the fluid far away from the surface is at rest. This flow problem is mathematically modelled and the non-Newtonian fluid under consideration obeys the rheological equation of state by the Casson model. A similarity transformation converts the governing nonlinear partial differential equations into nonlinear ordinary differential equations, which are solved analytically. Using the stream function and velocity components, these results are analyzed in dependence on the Casson fluid parameters, Chandrasekhar number, and mass transpiration parameters.

MHD卡森流体通过拉伸/收缩片的传质特性

摘要

本文分析了低电导率的Casson流体在拉伸/收缩片材上的稳定层流边界层流动，当远离表面的流体处于静止状态时，该拉伸/收缩片材在存在吸入/注入的情况下受到横向磁场作用。对流动问题进行了数学建模，所考虑的非牛顿流体通过卡森模型服从流变状态方程。相似变换将控制的非线性偏微分方程转换为非线性常微分方程，可以通过解析来求解。使用流函数和速度分量，根据卡森流体参数，钱德拉塞卡尔数和质蒸腾参数来分析这些结果。
