Radiation absorption and chemical reaction effects on MHD free convection flow heat and mass transfer past an accelerated vertical plate

In this paper we consider unsteady MHD natural convection flow heat and mass transfer of an
electrically conducting, viscous, incompressible fluid past an infinite vertical plate embedded in a
uniform porous medium in a rotating system taking Hall current in the presence of influence of
chemical reaction and radiation absorption effects into account. The expression for velocity,
temperature and concentration distribution, skin friction, rate of heat and mass transfer coefficients
at the plate are obtained using perturbation technique. The effect of various physical parameters
occurring into the problem discussed with the help of graphs.
