| dc.description.abstract | This study addresses the problem of unsteady free convection incompressible MHD fluid flow past
a semi-infinite vertical porous plate in the presence of a strong magnetic field inclined at an angle
to the plate with Hall and Ion-Slip currents. It investigates the effects of Grashof number, heat
source parameter, suction velocity, time, angle of inclination, Ion-Slip,Hall current and mass
diffusion parameteron the convectively cooled or convectively heated plate restricted to turbulent
boundary layer of the flow field.The partial differential equations governing the flow problem
considered in our study are solved by a finite difference approximation while the computation of
skin friction, rate of heat transfer and mass transfer at the plate is achieved by Newton’s
interpolation approximation over the first five points.The results show that the Hall current,
Schmidt number, Modified Grashof number, heat source parameter, suction velocity, time, angle of
inclination, Ion-Slip currenton the convectively cooled or convectively heated plate affect the
velocity, temperature and concentration profiles. Increases in Hall parameter cause a decrease in
both primary and secondary profiles while increase in Ion Slip current parameter leads to increase
in primary velocity profiles but a decrease in secondary velocity profiles. Consequently, their
effects alter the skin friction, rate of mass transfer and the rate of heat transfer.
