An analysis is carried out to study the flow and heat transfer characteristics on a continuous accelerated sheet extruded in a cross cooling steady stream of an incompressible viscoelastic fluid. A practical application of this problem is the cooling of extruded plastic sheets during the formation process. Results for skin‐friction and heat transfer coefficients are given. The effects of Reynolds, and Prandtl numbers, velocity difference, velocity ratio, velocity gradient, and viscoelastic parameter of both cooling stream and extruded sheet have been investigated and in an appropriate form using a suitable method of normalization. The power‐law constant for the wall temperature has considerable influence on the heat transfer mechanics.
