ABSTRACT
The magnetohydrodynamic (MHD) flow of a Newtonian fluid in a horizontal channel bounded by two parallel porous plates in the presence of inclined magnetic field has been investigated with the purpose of determining the effect of variation of Hartmann number, suction parameter and the magnetic inclination angle on velocity and temperature distribution. The flow is driven by the movement of the upper plate and a constant pressure gradient suddenly imposed in a direction parallel to the plates. The two plates are kept at different but constant temperature while joule and viscous dissipation are taken into consideration.Numerical solutions for the governing momentum and energy equations are obtained using finite difference approximation with appropriate initial and boundary conditions.The effect of change of the Hartmann number, suction parameter and the magnetic inclination angle on temperature and velocity profiles is then discussed. Accruing from the results is the fact the fluid velocity and the temperature distribution is influenced significantly by the changes in the above mentioned parameters. Firstly it was found that increase in Hartmann number led to decrease in both velocity and the temperature of the fluid. Secondly increasing the suction parameter led to reduction of flow velocity and the maximum temperature was found to move towards the moving plate. Lastly increasing the magnetic inclination angle was found to increase both velocity and the temperature of the fluid
