Thermal and mass diffusion on MHD natural convective flow of a rarefied gas along vertical porous plate.
Abstract
The flow of an electrically conducting incompressible rarefied gas due to the combined buoyancy effects of thermal and mass diffusion past an infinite vertical porous plate with constant suction has been studied in the presence of uniform transverse magnetic field. The problem has been solved for velocity, temperature, and concentration fields. It has been observed that mean velocity and the mean temperature are affected by the Grashof numbersG _{1} andG _{2}, the slip parameterh _{1}, temperature jump coefficienth _{2}, concentration jump coefficienth _{3} and magnetic field parameterM. The amplitude and the phase of skinfriction and the rate of heat transfer are affected by frequency in addition to the above parameters. They are shown graphically. The numerical values of the mean skinfriction and the mean rate of heat transfer are also tabulated.
