Heat and mass transfer in MHD unsteady free convective flow of a micro polar fluid over a vertical moving porous plate embedded in a porous medium in the presence of thermal radiation

An analysis is presented for the problem of heat and mass transfer in unsteady free convection flow of a micropolar viscous incompressible electrically conducting fluid over a vertical :moving porous non-conducting plate embedded in porous medium in the presence of transverse magnetic field and thermal radiation with time varying suction velocity. The plate moves with constant velocity in the longitudinal direction, and the free stream velocity follows an exponentially small perturbation law. In addition, the coefficient of skin-friction, and rate of heat transfer in terms of Nusselt number at the plate arc also derived, discussed, and their numerical values for the various values of physical parameters are presented through table.
