The effects of variable properties and hall current on steady MHD laminar convective fluid flow due to a porous rotating disk

摘要

The present investigation is concerned with the effects of variable properties [density (ρ), viscosity (μ) and thermal conductivity (κ)], Hall current (m), magnetic field (M) and suction/injection (W_s) on steady MHD laminar flow of an electrically conducting fluid on a porous rotating disk in presence of a uniform magnetic field. The fluid properties are taken to be strong functions of temperature. The induced magnetic field is neglected while the electron-atom collision frequency is assumed to be relatively high, so that the Hall effect is assumed to exist. The dimensionless steady governing equations are then solved numerically by using Runge-Kutta and Shooting method, and the effects of the relative parameters are examined.
