The objective of the present work is to investigate theoretically the Hiemenz flow and heat transfer of an incompressible viscous nanofluid past a porous wedge sheet in the presence of suction/injection due to solar energy (incident radiation). The wall of the wedge is embedded in a uniform Darcian porous medium in order to allow for possible fluid wall suction or injection and has a power-law variation of the wall temperature. The partial differential equations governing the problem under consideration are transformed by a special form of Lie symmetry group transformations viz. one-parameter group of transformation into a system of ordinary differential equations, which are solved numerically using Runge-Kutta-Gill based shooting method. The conclusion is drawn that the flow field and temperature are significantly influenced by thermal radiation, nanoparticle volume fraction, and porosity of the sheet.
