STUDY ON SIMILARITY SOLUTIONS FOR MHD VISCO - ELASTIC FLOW WITH HEAT AND MASS TRANSFER OVER A PERMEABLE STRETCHING SHEET EXTRUDED IN A CROSS COOLING STREAM WITH HEAT SOURCE/SINK

Study of similarity solutions for flow with heat and mass transfer characteristics on a continuous accelerated sheet extruded in a cross - cooling steady stream of an incompressible visco - elastic (Walter's liquid B') fluid is a analysed. An industrial appli cation of this type of problem is the cooling of extruded plastic sheet during formation process. The effects of various physical parameters encountering in the study like visco - elasticity, Reynold's number, Prandtl number Shrewood number, and velocity r atio are investigated in an appropriate form using suitable analytical methods. Results for skin friction, heat transfer co - efficient and mass transfer co - efficient are obtained. The power law constant for wall temperature and wall concentration have an effective influence on heat and mass transfer mechanics.
