RADIATIVE EFFECTS ON TRANSIENT FREE CONVECTIVE HEAT TRANSFER PAST AN EXPONENTIALLY ACCELERATED HOT VERTICAL SURFACE IN POROUS MEDIUM IN THE PRESENCE OF MAGNETIC FIELD

摘要

Radiative effects on transient free convective heat transfer past an exponentially accelerated hot vertical surface in porous medium in the presence of magnetic field has been studied. The fluid is assumed to be gray, emitting-absorbing with non-scattering medium having optically thick radiation limit. The dimensionless governing equations are solved using Laplace transform technique. The results are obtained for velocity, temperature, Nusselt number, and shearing stress for different parameters like time, magnetic parameter, radiation parameter, etc. The flow characteristics are shown by means of graphs with vivid discussion.
