Hydromagnetic Turbulent Flow Past A Semi-Infinite Vertical Plate Subjected To Heat Flux

Abstract

In this study we have investigated a turbulent flow of a rotating fluid past a semi-infinite vertical porous plate subjected to a constant heat flux. A variable magnetic field is applied transversely in the direction normal to the plate. An induced electric current known as Hall current exists due to the presence of both electric field and magnetic field. The differential equations governing this problem are solved numerically using a finite difference scheme. Further we have investigated the effects of various parameters on the velocity, temperature, magnetic field and concentration profile. The skin friction the rate of heat transfer and the rate of mass transfer is calculated using Newton’s interpolation formula We noted that the Hall current, rotation parameter, Eckert number, injection and Schmidt number affect the velocity, temperature magnetic field and concentration profiles.
