A Study on Unsteady Magneto-Hydrodynamics (Mhd) Free Convective Flow Past a Vertical Oscillating Plate Through a Porous Medium in the Presence of Heat Source

Abstract

This study investigate time dependent MHD natural convective flow past a vertical oscillating plate through a porous medium in the  presence of heat source. The governing differential equations of the flow characteristics are solved numerically by using the implicit finite  difference scheme. The results obtained for the velocity, temperature and concentration were analysed. The effects of different  physical parameters appear on the present situation such as Prandtl number (Pr), Schmidt number (Sc), thermal Grashof number (Gr),  mass Grashof number (Gc), radiation (R), magnetic field (M), Time (t) and Heat source (Q) were presented graphically and discussed in  detail. It is observed that the fluid velocity significantly increases as the value of Grashof number (Gr), mass Grashof number (Gc),  Permeability parameter (K) and Time (t) increased, while the opposite phenomenon is noticed for growing values of magnetic field  parameter (M), Prandtl number (Pr), radiation parameter (R), Schmidt number (Sc) respectively.
