Numerical simulations of Williamson fluid containing hybrid nanoparticles via Keller box technique

Abstract In this investigation, a Williamson hybrid nanoliquid flow over a stretchy surface has been considered. Furthermore, the convective boundary condition is incorporated for the analysis. In view of the practical applications thermal radiation is used to analyze the energy transfer phenomenon. The momentum and energy expressions are solved numerically by employing the KB approach (Keller Box Technique). The energy transfer rate has been discussed in the table. Further, velocity, temperature and Nusselt number impacts against thermal radiations are discussed in detail. This research portrayed that with the growth of suction/injection factor, the energy transmission and skin friction increase. Moreover, the heat transfer rate decreases for both $${(Al}_{2}{O}_{3}+CuO)/SA$$ ( A l 2 O 3 + C u O ) / S A and $${Al}_{2}{O}_{3}/SA$$ Al 2 O 3 / S A the on the growth of Weissenberg parameter. In the same vain heat transfer rate improves for the increment in the convective parameter.
