    Free convection effects on mhd flow past an infinite vertical accelerated plate embedded in porous media with constant heat flux.
    (2011-10-13) Chaudhary, R. C.; Goyal, M. C.; Jain, A.
    This paper analyses the free convection flow of a viscous incompressible fluid past an infinite vertical accelerated plate embedded in porous medium with constant heat flux in the presence of transverse magnetic field. The governing equations are solved in closed form by Laplace transform technique. The results are obtained for velocity, temperature, skin-friction and Nusselt number. The effects of M-magnetic field parameter, Pr-Prandtl number, G-Grashof number, K-permeability parameter are discussed on the flow variables and presented by graph.

    Influence of periodic temperature and concentration on unsteady free convective viscous incompressible flow and heat transfer past a vertical plate in slip-flow regime.
    (2011-10-13) Kumar Sharma, Pawan
    An effect of periodic temperature and concentration on unsteady free convective, viscous incompressible flow and heat transfer in slip-flow regime is carried out. Assuming variable suction at the plate, approximate solutions are obtained for velocity, skin-friction, temperature, heat transfer and concentration. During the course of discussion, the effects of Gr (Grashof number based on temperature), Gc (modified Grashof number based on concentration difference), A (suction parameter) and [omega] (frequency parameter) for carbon dioxide (Sc = 0.94) in air (Pr = 0.71) are presented and discussed graphically
