Abstract:

The present study considers a non-Newtonian flow over a horizontally immersed flat plate kept at a different temperature relative to the fluid. An inviscid free stream with uniform velocity induces the flow over the plate where an incompressible boundary layer viscously occurs. It is stipulated that the fluid obeys the Carreau-Yasuda constitutive equation. Analytical investigations begin with the derivation of momentum and energy equations followed by boundary layer simplifications. Scaling symmetries are subsequently calculated to define similarity variables to transform boundary layer equations into ordinary differential forms. Later, solutions of the governing equations are pursued by a numerical scheme based on finite differences. Thanks to those solutions, the effects of significant non-dimensional parameters, such as Deborah and Prandtl numbers, on both momentum and thermal boundary layers are examined throughout the figures. The Nusselt number's variation with non-dimensional numbers is also questioned for the study's heat transfer part.
