P. K. Singh . Mixed Convection Boundary Layer Flow past a Vertical Plate in Porous Medium with Viscous Dissipation and Variable Permeability. International Journal of Computer Applications. 48, 8 ( June 2012), 45-48. DOI=10.5120/7372-0216
Mixed convection boundary layer flow, over an isothermal vertical plate, of an incompressible and viscous fluid with variable thermal conductivity is studied in the present paper . The convective flow is taking place in such a porous medium whose permeability is assumed to be spatially variable. The mixed convective flow is due to the simultaneous effects of (1) free stream along the plate and (2) the buoyancy force caused by the variations in density due to temperature difference. The effects of viscous dissipation have been taken into account and the partial differential equations governing the boundary layer flow are converted into to a system of ordinary differential equations by using suitable similarity transformations. These equations are solved numerically and effects of various parameters such as , and Eckert number etc. on the flow fields are investigated and presented graphically.
