The main aim of the above three papers is to study the effects of secondorder
slip and viscous dissipation on the boundary layer flow and heat transfer
of an incompressible Newtonian fluid past a permeable stretching surface
embedded in a porous medium using the implicit finite difference method
(FDM) in the first paper[1] , the differential transformation method (DTM) in
the second paper [2] and Chebyshev finite difference method in the third paper
[3] .
It is known that the heat transfer results may alter appreciably due to
viscous dissipation in two cases namely: (i) the fluid is very viscous even
though low speed velocity i.e. liquid fluids and (ii) high speed velocity. While
in the case of high speed velocity, the rigid matrix resistance is no longer given
by Darcy's law, i.e. the velocity – square term in the momentum equation (3)
becomes significant [ 4 ] . |
