| Summary: | An analysis is presented to investigate the
effect of thermophoresis particle deposition and temperature
dependent viscosity on unsteady non-Darcy
mixed convective heat and mass transfer of a viscous
and incompressible fluid past a porous wedge in the
presence of chemical reaction. The wall of the wedge
is embedded in a uniform non-Darcian porous medium
in order to allow for possible fluid wall suction or injection.
The governing partial differential equations of
the problem, subjected to their boundary conditions,
are solved numerically by applying an efficient solution
scheme for local nonsirnilarity boundary layer
analysis. Numerical calculations are carried out for
different values of dimensionless parameters arising
in the problem. The results are compared with available
ones in the literature and excellent agreement is
obtained. An analysis of the obtained results shows
that the flow field is influenced appreciably by the
chemical reaction and thermophoresis particle deposition. |
