Abstract
An unsteady flow and heat transfer problem with viscous dissipation of a third order fluid placed within two long parallel flat porous
walls is studied in present work. The governing equations are non- dimensionalized and finally a non-linear coupled system of partial differential
equation is obtained. An approximated solution is obtained using finite
difference method of fully implicit form. With help of high speed MATLAB programming numerical solution is procured and presented graphically. Investigation is made on effect of different physical parameters
on flow and heat profile. The notable finding in the current work is that
for smaller values of visco-elastic parameter α, the velocity rises with
raising the values of α. But for larger visco-elastic parametric values
of α, a reversed effect is seen on velocity field. Also with the increase
of viscous-dissipation parameter, more viscous-dissipation heat generated
that increases the temperature field.
