EFFECTS OF HALL CURRENT, ROTATION AND INCLINED MAGNETIC FIELD ON A FLUID FLOWING OVER POROUS PARALLEL VERTICAL PLATES WITH HEAT AND MASS TRANSFER

Abstract

An unsteady incompressible Magnetohydrodynamics (MHD) boundary flow of an electrically conducting fluid between two parallel vertical plates was considered. A strong, steady and inclined magnetic field of strength  was applied into the fluid region. The coupled non-linear partial differential equations governing the flow were first non-dimensionalized then solved using the finite difference method. Numerical values were simulated using the Matlab program. The profiles for velocity, temperature and concentration were demonstrated graphically for various values of the parameters  for Hall current,  for angular velocity of the system,  for the suction velocity at the plate and  for the Sine of the angle α of application of the magnetic field. The results were then interpreted physically to provide important insights in geophysical fluid dynamics. It was found that the primary velocity decreases at various rates from maximum at the left plate to zero away from the plate for various values of parameters and  .As distance from the left plate increases, the secondary velocity decreases to a critical value then increases to a maximum constant value for various values of parameters  and . The temperature and concentration decreases at various rates from a maximum value at the left plate to zero away from the plate for various values of
