Abstract

In this paper an analysis is presented to investigate the influence of diffusion thermo, thermal radiation, radiation absorption, chemical reaction and viscous dissipation on hydro magnetic free convective heat and mass transfer flow of Kuvshinski fluid past a porous vertical plate. A uniform magnetic field of is applied in the direction of the flow field. Analytical solutions for velocity, temperature and concentration are obtained by using a Perturbation technique. Skin friction, rate of heat and mass transfer coefficients are also derived. The results have been analyzed graphically and numerically for various values of the flow parameters.
