Thermal boundary layer over a vertical plate in porous medium with a convective surface boundary condition

This study aims to investigate the thermal boundary layer over a vertical plate in porous medium with a convective surface boundary condition. The governing systems of partial differential equations subject to the boundary conditions are transformed into the system of ordinary differential equati...
