Abstract
•Three-dimensional flow of second grade fluid is modeled.•Flow is bounded by a bidirectional stretching surface.•Cattaneo–Christov heat flux theory is utilized.•Series solutions are developed by homotopy analysis method (HAM).
The present article addresses the three-dimensional flow of second grade fluid over a stretching surface with Cattaneo–Christov heat flux. Heat transfer characteristics for Cattaneo–Christov heat flux characterize the properties of thermal relaxation. Mathematical formulation is made using boundary layer approach. Similarity variables lead to a nonlinear differential system. System is solved for the convergent series solutions of velocity and temperature distributions. Effects of interesting flow parameters on the velocities and temperature distributions are plotted and discussed. Skin friction coefficients and heat transfer rate are also computed and examined. We observed that the temperature field has an inverse relationship with the thermal relaxation parameter and the Prandtl number.
