摘要：In this paper the effect of slip condition, chemical reaction and radiation on a transient magneto-hydrodynamic periodic flow of a viscous, incompressible, electrically conducting fluid through a porous medium in the presence of transverse applied magnetic field is discussed in detail considering in two cases viz. Case–I: Uniform plate Temperature and Uniform Concentration and Case–II: Constant heat and mass flux.. The governing equations describing the flow have been solved by perturbation technique and the solutions for velocity, temperature and concentration are obtained. The skin friction and rate of heat transfer and mass transfer are also derived. The effects of various physical parameters like magnetic parameter M, Reynolds number Re, Grashof number Gr, modified Grashof number Gm, permeability parameter k, chemical reaction parameter kc, and Schmidt number Scare analyzed though graphs. It is observed that in both the case the velocity increases with an increase in slip parameter h, Grashof number Gr, modified Grashof number Gm, Schmidt number Sc, and Radiation parameter F where as it shows a reverse effect in the case of magnetic parameter M, time t, permeability parameter k or Reynolds number Re.
