考虑了运动的可伸缩薄板服从更一般的伸展定律的流动。薄片占据负x轴，并在不可压缩的粘性和导电流体中沿正x方向连续移动。薄片不知何故消失在位于(x，y)=(0，0)的水槽中。首先将偏微分方程组转化为常微分方程组，然后利用有限差分格式，即Keller-box法对变换后的方程进行数值求解。分析和讨论了不同调节参数取值时的流动和换热特性。结果表明，在x=0附近，速度分布呈反向流动，存在对偶解。
The flow due to a moving extensible sheet that obeys a more general stretching law is considered. The sheet occupies the negative x-axis and is moving continually in the positive x-direction, in an incompressible viscous and electrically conducting fluid. The sheet somehow disappears in a sink that is located at (x, y) = (0, 0). The governing system of partial differential equations is first transformed into a system of ordinary differential equations, and the transformed equations are solved numerically using a finite-difference scheme, namely the Keller-box method. The features of the flow and heat-transfer characteristics for different values of the governing parameters are analyzed and discussed. It is found that dual solutions exist for the flow near x = 0, where the velocity profiles show a reversed flow.
