An analysis is made to study MHD flow and heat transfer for Maxwell fluid
over an exponentially stretching sheet through a porous medium in the
presence of non-uniform heat source/sink with variable thermal conductivity.
The thermal conductivity is assumed to vary as a linear function of
temperature. The governing partial differential equations are transformed
into ordinary differential equations using similarity transformations and
then solved numerically using implicit finite difference scheme known as
Keller-box method. The effect of the governing parameters on the flow field,
skin friction coefficient, wall temperature gradient (in prescribed surface
temperature case), wall temperature (in prescribed heat flux case) and
Nusselt number are computed, analyzed and discussed through graphs and
tables. The present results are found to be in excellent agreement with
previously published work [1,2] on various special cases of the problem.
