Abstract

An analys is was presented to investigate the effects of variable viscosity and thermal stratification on MHD mixed convective heat and mass transfer of a viscous, incom pressible and electrically conducting fluid past a porous wedge in the presence of chemical reaction. The wall of the wedgewas embedded in a uniform non-Darcian porousmedium in order to allow for possible fluid wall suction or in jection. The governing boundary layer equations were written into a dmiension less form by smiilarity transformations. The transformed coupled nonlinear ordinary differential equations were solved numerically by using finite difference methods. Numericalcal-culations up to third order level of truncation were carried out for different values of dmiensionless parameters. The results are presented graphically and the conclusion is drawn that the flow field and other quantities of physical interest are significantly in fluenced by these parameters. The results are compared with those known from the literature and excellent agreement between the results is obtained.
