Similarity transformation followed by shooting technique using Runge-Kutta 4 th order method is adopted for analyzing this problem. Particle electrification and the effect of a heat source/sink are included in the set of influencing parameters to understand the flow characteristics. From this investigation it is observed that the higher electrification parameter is to reduce the normalized fluid temperature and to enhance the normalized particle temperature in the presence of heat source, whereas the trend is reversed in the presence of heat sink.

INTRODUCTION The theoretical study of boundary layer flows induced by a stretching sheet is of considerable interest because of their applications in fibers spinning, manufacturing of plastic and rubber sheets, the aerodynamics extrusion of plastic sheets, hot rolling and cooling of an infinite metallic plate in a cooling bath. It has also numerous applications in industrial manufacturing processes such as wire drawing, glass-fiber and paper production, crystal growing, cable coating and many other to get end product of desired quality and parameter.
