Magnetohydrodynamic ow of a hot viscous
electrically conducting incompressible uid through
parallel plates is studied. In the study, the e ect of
Hartmann number (M), pressure gradient and
Reynolds number (Re) on the velocity eld is
investigated. The Navier-stokes equations were coupled
with Ohms law and then solved using nite di erence
method (FDM). The velocity eld was computed for various values of the physical parameters and shown
graphically. It was found that as the Hartmann number
M increases, the velocity pro les decreased due to
increased Lorents force while an increase in Reynolds
number causes an increase in the velocity of the uid. All
these analysis was done using MATLAB program and
the results were presented in tables and graphs.
