Abstract
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.
