• HYDROMAGNETIC FREE CONVECTIVE OSCILLATORY COUETTE FLOW THROUGH A POROUS VERTICAL CHANNEL WITH PERIODIC WALL TEMPERATURE

Khem Chand*, Sapna Jain

Abstract


The unsteady Couette flow of a viscous incompressible fluid through a highly porous medium bounded by two vertical parallel porous plates in the presence of transversely applied magnetic field has been studied. One of the plate is suddenly moved from rest with a free stream velocity that oscillates in time about a constant mean. Assuming periodic temperature at the moving plate, the approximate solution for the velocity field, the temperature field, the skin friction and the rate of heat transfer are obtain by using perturbation technique and discussed with the help of graphs and tables.


Keywords


Hydromagnetic, unsteady free convective, periodic wall temperature.
