The flow is considered in porous medium past an oscillating, infinite porous horizontal plate in slip flow regime under the influence of transverse magnetic field of uniform strength. Exact solutions for velocity, temperature and concentration field are obtained. The expressions for skin-friction, heat and mass transfer rate are also derived. The results obtained are numerically presented through graphs or tabular form followed by discussion.</p> https://ultraphysicalsciences.org/paper/1396/ Unsteady MHD mass transfer porous medium oscillating porous horizontal slip flow regime
