Hall Effects on Hydromagnetic Flow on an Oscillating Porous Plate

Department of Applied Mathematics, Vidyasagar University, Midnapore 721 102, India

摘要

摘要: 以无限多孔扁平板为边界，对不可压缩导电粘滞流体的不稳定流动进行了分析．平板在其自身平面内以频率n作谐振动，在流体流动的垂直方向上作用一均匀磁场．研究发现，平板上有吹出（速度）时，问题的解依然存在．还得到了考虑粘性及Joule耗散时的温度分布．壁面的平均温度随着Hall参数的增大而减小．可以发现，平板上有吹出（速度）时，不存在温度分布．

Abstract: An analysis was made on the unsteady flow of an incompressible electrically conducting viscous fluid bounded by an infinite porous flat plate.The plate executes harmonic oscillations with frequencyn n in its own plane.A uniform magnetic field is imposed perpendicular to the direction of the flow.It is found that the solution also exists for blowing at the plate.The temperature distribution is also obtained on taking viscous and Joule dissipation into account.The mean wall temperature decreases with increase in Hall parameter.It is found that no temperature distribution exists for the blowing at the plate.
