Free Convective MHD Flow of a Non-Newtonian Fluid Past An Infinite Vertical Plate with Constant Suction and Heat Sink

The free convective MHD flow of a non-Newtonian electrically conducting fluid past an infinite vertical porous plate in the presence of constant suction and heat absorbing sinks has been discussed. To obtain the solutions for the velocity and temperature fields, mean skin-friction and mean rate of heat transfer the multi-parameter perturbation approximation is used. Expressions for dimensionless velocity, temperature, mean skin-friction and mean rate of heat transfer at the plate have been obtained and numerically worked out for different values of parameters involved in the solution. The mean skin-friction and mean rate of heat transfer have been presented numerically and the dimensionless velocity and dimensionless temperature have been presented graphically for various values of non-Newtonian parameters.
