Effect of Hall Currents and Variable Fluid Properties on MHD Flow past Stretching Vertical Plate by the Presence of Radiation

Abstract

This paper investigates the effects of Hall currents and radiation on free-convective steady laminar boundary-layer flow past a semi-infinite vertical plate for large temperature differences. A uniform magnetic field is applied perpendicular to the plate. The fluid density is assumed to vary exponentially and the thermal conducting linearly with temperature. The fluid viscosity is assumed to vary as a reciprocal of a linear function of temperature. The usual Boussinesq approximation is neglected. The nonlinear boundary layer equations governing the problem under consideration are solved numerically by applying an efficient numerical technique based on the shooting method. The effects of the magnetic parameter Μ , the Hall parameter m, the density/temperature parameter n , the radiation parameter Ν , the thermal conductivity parameter S , the viscosity temperature θ r , and the temperature ratio parameter θ w are examined on the velocity and temperature distribution as well as the coefficient of heat flux and shearing stress at the plate.

Influence of Dofour and Soret on Eyrig-Powell Nanofluid Flow from A Circular Cylinder with Viscous Dissipation

“…Free convection flows past a semi-infinite vertical plate under different physical conditions have been studied by [1]. Reference [2] studied the effect of Hall currents, radiation and variable viscosity on free convective flow past a semi-infinite continuously stretching plate, [3] studied the effect of Hall currents and variable fluid properties on MHD flow past a continuously stretching vertical plate in the presence of radiation. Due to the important role of Viscous dissipation in natural convection in processes subjected to big contrast of gravitational force or devices which operate at high speeds, viscous dissipation effect on MHD flow attracted the interest of many researchers.…”

“…There are many researches to study the behavior of non-Newtonian fluids. Reference [16] analyzed the Combined Effects of Hall Current and Variable Viscosity on Non-Newtonian MHD Flow Past a Stretching Vertical Plate.…”

“…Jaber [16] studied the effect of Hall currents, and variable viscosity on free convective flow past a semi-infinite continuously stretching plate in presence of radiation. Jaber [17] studied the effect of Hall currents and variable fluid properties on magneto hydrodynamics flow past a continuously stretching vertical plate in the presence of radiation. Viscous dissipation effect plays an important role in natural convection in various devices which are subjected to large variations of gravitational force or which operate at high speeds Jaber [18] examined the effects of viscous dissipation and joule heating on magneto hydrodynamics flow of a fluid with variable properties past a stretching vertical plate.…”
