“…The thermal radiation interaction on an absorbing emitting fluid past a vertical porous plate immersed in a porous medium has been reported by Samad and Rahman [7]. The heat and mass transfer of an unsteady MHD natural convective flow of a rotating fluid past a vertical porous flat plate in the presence of radiative heat transfer have been studied by Mbeledogu and Ogulu [8]. Beg and Ghosh [9] have investigated hydromagnetic free and forced convection of an optically-thin gray gas from vertical flat plate subject to a surface temperature oscillations with significant thermal radiation.…”

Combined effects of Hall currents and radiation on an unsteady MHD free convective flow past a vertical flat plate with oscillatory plate temperature in a porous medium have been studied. The governing equations are solved analytically in closed form. The results obtained are presented graphically. It is found that the Hall currents accelerate the fluid velocity components whereas the radiation has a tendency to retard the fluid velocity components. Porosity of the medium has a tendency to enhance the fluid velocity components. Hall currents reduce the amplitude of the shear stress at the plate due to the unsteady primary flow whereas they increase the amplitude of the shear stress at the plate due to the unsteady secondary flow. Further, the rate of heat transfer at the plate due to unsteady flow increases with an increase in either radiation parameter or Prandtl number or frequency parameter.

“…This provoked quite a lot of researchers to carry out a capacious volume of research works on unsteady hydromagnetic rotating flow near a vertical plate under various conditions. Mentions may be made of the research works of Singh (1984), Raptis and Singh (1985), Bestman and Adjepong (1988), Mbeledogu and Ogulu (2007).…”

A study on unsteady MHD natural convection flow of an optically thin, heat radiating, incompressible, viscous, chemically reactive, temperature dependent heat absorbing and electrically conducting fluid past an exponentially accelerated infinite vertical plate having ramped temperature, embedded in a porous medium is carried out, considering the effects of Hall current and rotation. Governing equations are non-dimensionalized and Laplace Transform Technique is used to find the exact solutions for non-dimensional velocity, temperature and concentration fields. The quantities of physical interest i.e. shear stress at the plate, rate of heat and mass transfers at the plate are also derived. Numerical results for the velocity, temperature and species concentration of the fluid are demonstrated with the help of graphs whereas those of shear stress at the plate, rate of heat and mass transfers at the plate are displayed in tables for various flow parameters. It is observed that fluid velocities as well as fluid temperature profiles are slower in case of ramped temperature plate than those of isothermal plate.
