In this study, we present a steady three-dimensional magnetohydrodynamic
(MHD) flow and heat transfer characteristics of a viscous fluid due to a
bidirectional stretching sheet in a porous medium. The heat transfer analysis
has been carried out for two heating processes namely (i) the prescribed
surface temperature (PST) and (ii) prescribed surface heat flux (PHF). In
addition the heat transfer rate varies along the surface. The similarity
solution of the governing boundary layer partial differential equations is
developed by employing homotopy analysis method (HAM). The quantities of
interest are velocity, temperature, skin-friction and wall heat flux. The
results obtained are presented through graphs and tabular data. It is
observed that both velocity and boundary layer thickness decreases by
increasing the porosity and magnetic field. This shows that application of
magnetic and porous medium cause a control on the boundary layer thickness.
Moreover, the results are also compared with the existing values in the
literature and found in excellent agreement.
