“…The mixed influence of thermal radiation and buoyancy force was considered by Pal and Mondal (2011) on steady two dimensional MHD laminar flow of an incompressible viscous fluid which has electrically conducting feature past a vertical stretching material in a porous medium. The MHD model of fluid flow with electrically conducting property past a stretching material has many applications in extrusion processes, petroleum industry, purification of crude oil, fluid droplets, continuous coating, hot rolling, production of plastic sheets, foils, polymer technology, glass blowing, fibers spinning, rubber sheets and cold drawing of plastic sheets (see Vajravelu et al, 2011;Rosea and Pop 2010;Kandasamy et al, 2005; Abd El-Aziz 2009).…”
