摘要

研究了旋转系统中具有霍尔电流的无限大非导电垂直平面在多孔介质中的自由对流振荡。将模型的控制方程转化为无因次形式。利用拉普拉斯变换方法得到了速度和温度的解析解。本文用图表说明了各参数对温度、表面摩擦和速度的影响。观察到平板振荡、多孔介质、辐射和霍尔电流的变化对流体运动有显著影响。此外，表面附近的皮肤摩擦随着辐射参数的增加而增加。所得结果在工程和科学领域具有重要意义。

MHD Free Convective Flow along Vertical Oscillatory Plate with Radiative Heat Transfer in the Presence of Hall Current and Heat Source

MHD free convective flow with oscillations of an infinite non-conducting vertical flat surface through a porous medium with Hall current in a rotating system was studied. The governing equations of the model were converted into dimensionless form. Analytical solutions for velocity and temperature were obtained with the help of the Laplace transform method. Graphs and tables are used in this paper to show the influence of various parameters on temperature, skin friction and velocity. It was observed that changes in plate oscillation, porous medium, radiation and Hall current have significant effects on fluid motion. Further, the skin friction near the surface is increased by the radiation parameter. The results obtained have large implications in the engineering and science fields.
