Abstract:

This work addresses visco-elastic boundary layer flow and heat transmission over a stretching sheet in the presence of viscous dissipation and a nonuniform heat source. Analytical solutions exist for highly non-linear momentum equations and heat transfer equations with confluent hypergeometric similarity. Here, two types of different heating procedures are considered: prescribed surface temperature (PST) and prescribed wall heat flux (PHF). A number of parameters, such as the visco-elastic parameter, Eckert number, Prandtl number, and non-uniform heat source/sink parameter, are analyzed in connection to the temperature distribution. Each of these parameters\' effects on the wall temperature gradient and wall temperature are enumerated and described.
