Effects Of Hall Currents And Variable Fluid Properties On Mhd Flow Past Stretching Vertical Plate

The effects of Hall currents on free-convective steady laminar flow of fluid of variable properties, along a semi-infinite vertical plate for large temperature differences, in the presence of Hall current has been investigated. The fluid density is vary exponentially and the thermal conducting linearly with temperature, while the fluid viscosity is vary as a reciprocal of a linear function of temperature. The usual Boussinesq approximation is neglected. The sysem of nonlinear equations governing the problem under consideration transformed into non-similar partial differential equations which have been solved numerically by the forth-order Runge-Kutta method. The effects of the magnetic parameter M, the Hall parameter m, the density / temperature parameter n, the thermal conductivity parameter S, the viscosity temperature , and the temperature ratio parameter on the velocity and temperature distribution as well as the coefficient of heat flux and shearing stress at the plate are investigated.
