摘要:
对具有热传递的沿半无限平板的磁弹性粘性流的群方法分析的评论,Helal和Abd-el-Malek,计算与应用数学杂志173(2005)199-210。本文讨论了在横向磁场作用下弹粘液体沿无限平板的边界层流动。板温度高于环境流体温度。用群论方法将边界层方程组转化为普通方程组,然后进行数值求解。速度,温度,剪切应力和热传递的轮廓的磁参数M=0,0.5和1的值。这是一个有趣的工作,但也有一些基本的错误,这是下面提出的。
英文摘要:
Comment on Group method analysis of magneto-elastico-viscous flow along a semi-infinite flat plate with heat transfer,Helal and Abd-el-Malek, Journal of Computational and Applied Mathematics 173 (2005) 199-210. In the above paper the authors treat the boundary layer flow of a elasto- viscous liquid along an infinite plate in the presence of a transverse magnetic field. The plate temperature is higher than the ambient fluid temperature. The boundary layer equations are transformed into ordinary ones using the group theory and subsequently are solved numerically. Velocity, temperature, shear stress and heat transfer profiles are presented for values of magnetic parameter M=0, 0.5 and 1. This is an interesting work but there are some fundamental errors which are presented below.
