摘要

摘要本文分析了在存在传热的情况下，相对于旋转流体经过加速水平板时的霍尔电流和旋转。给出了霍尔参数、哈特曼数、旋转参数(无量纲角速度)、格拉索夫数和普朗特数对轴向和横向速度分布的影响。发现随着哈特曼数的增加，轴向和横向速度分量的增加方向与增大霍尔参数和旋转参数的方向相反。当Ω=M2m /(1 + m2)时，横向速度分量消失，轴向速度达到最大值。

Hall Effects on Mhd Flow Past an Accelerated Plate with Heat Transfer

Abstract Hall current and rotation on an MHD flow past an accelerated horizontal plate relative to a rotating fluid, in the presence of heat transfer has been analyzed. The effects of the Hall parameter, Hartmann number, rotation parameter (non-dimensional angular velocity), Grashof’s number and Prandtl number on axial and transverse velocity profiles are presented graphically. It is found that with the increase in the Hartmann number, the axial and transverse velocity components increase in a direction opposite to that of obtained by increasing the Hall parameter and rotation parameter. Also, when Ω=M2m /(1 + m2 ) , it is observed that the transverse velocity component vanishes and axial velocity attains a maximum value.
