On convective dusty flow past a vertical stretching sheet with internal heat absorption

The steady two-dimensional boundary layer flow of a viscous,incompressible,and electrically conducting dusty fluid past a vertical permeable stretching sheet under the influence of a transverse magnetic field with the viscous and joule dissipation is investigated. the fluid particles are assumed to be heat absorbing and the temperature at the surface of the sheet is a result of convective heating. the governing nonlinear partial differential equations are transformed to a set of highly nonlinear coupled ordinary differential equations using a suitable similarity transformation and the resulting system is then solved numerically. it is found inter alia that the contributions of viscous and joule dissipation in the flow are to increase the thickness of the thermal boundary layer. © 2013 raj nandkeolyar and precious sibanda.
