“…Mbeledogu and Ogulu (2007) obtained analytical closed form solution of unsteady hydromagnetic natural convection flow of a rotating, incompressible, viscous Boussinesq fluid in the presence of radiative heat transfer and first order chemical reaction. The influence of radiation and rotation on unsteady hydromagnetic free convection flow past an impulsively moving infinite vertical plate with ramped temperature in a porous medium is investigated by Seth et al (2013). Jonah Philliph et al (2014) considered the problem of rotating magnetohydrodynamic heat and mass transfer free convection flow past an exponentially accelerated isothermal vertical plate in the presence of variable mass diffusion.…”

“…Although these system parameters play significant role in determining the flow features of the hydromagnetic natural convection flows. Seth et al (2014) extended the works of Seth et al (2013) and Jonah Philliph et al (2014) and investigated the influence of Hall current, permeability of the medium, heat absorption/radiation and chemical reaction on hydromagnetic natural convection flow past an impulsively moving isothermal vertical plate with uniform species concentration. Seth et al (2015) considered the influence of Hall current, permeability and heat absorption on hydromagnetic natural convection flow past an exponentially accelerated vertical plate with ramped plate temperature but they have not considered the effect of rotation and species concentration in their problem.…”

In the present analytical study, we have considered unsteady hydromagnetic heat and mass transfer natural convection flow of an electrically conducting, heat absorbing and chemically reacting fluid past an exponentially accelerated vertical plate in a uniform porous medium taking Hall current and rotation into account. The species concentration near the plate is considered to be varies linearly with time. Two particular cases for plate temperature are considered i.e. (i) plate temperature is uniform and (ii) plate temperature varies linearly with time and after some time it is maintained at uniform temperature. The coupled partial differential equations governing the fluid flow problem are solved analytically for fluid velocity, temperature and species concentration using Laplace transform method. To examine the physical characteristic of this problem the graphs for velocity, temperature, species concentration, skin friction, Nusselt number and Sherwood number distributions are computed and generated for various values of different pertinent flow parameters. It is observed that for small thermal diffusion, the free stream value of velocity and temperature are achieved nearer to the plate in comparison to that for large thermal diffusion.

Seth et al 26 investigated on unsteady MHD natural convection flow with heat and mass transfer of an electrically conducting viscous incompressible chemically reactive and optically thin heat radiating fluid through a saturated porous medium past an infinite moving vertical plate with arbitrary ramped temperature. It is found that, for isothermal plate, the fluid temperature and, the rate of heat transfer at isothermal plate approaches steady state when 1.5 t  .…”

In this manuscript a study of the unsteady magneto-hydrodynamic mixed convection Jeffrey fluid flow over an inclined permeable moving plate in presence of thermal radiation, heat generation, thermophoresis effect and homogenous chemical reaction, subjected to variable suction has been undertaken. The governing equations are solved by using a regular perturbation technique. The expressions for the distributions of velocity, temperature and species concentration are obtained. With the aid of these, the expressions for skin friction, Nusselt number and Sherwood number also have been derived. The influences of various physical parameters involved in the problem on the above mentioned quantities are discussed with the help of graphs and tables. From the significant findings, it has been found that the velocity increases with an increase in Soret number in the presence of permeability. It shows reverse effects in the case of heat absorption coefficient, magnetic parameter, radiation parameter and chemical reaction parameter.Keywords
