The steady three–dimensional flow of a dusty fluid towards a stretching sheet is investigated by using similarity solution approach. The free stream, along z-direction impinges on the stretching sheet to produce a flow with different velocity components. The governing equations are transformed into ordinary differential equations by introducing appropriate similarity variables and an exact solution is obtained. The nonlinear ordinary differential equations are solved numerically using Runge- Kutta fourth-order method. The effects of the physical parameters like velocity ratio, fluid and thermal particle interaction parameter, ratio of free-stream velocity parameter to stretching sheet velocity parameter, on the flow field characteristics are obtained, illustrated graphically and discussed. Also, a comparison of the obtained numerical results is made with two- dimensional cases existing in the literature and good agreement is approved. Moreover, it is found that the heat transfer coefficient and shear-stress on the surface for axisymmetric case are larger than non-axisymmetric case. Also, for stationary flat plat case, a similarity solution is presented and a comparison of the obtained results is made with previously published results and full agreement is reported.
