Abstract

One of the modern methods to increase heat transfer in fluids is the use of Hybrid nanoparticles instead of nano- particle. Therefore, in this paper mahnetohydrodynamic (MHD) flow and heat transfer of non-Newtonian micropolar dusty fluid suspended Cu-Al 2 O 3 Hybrid nanoparticles past a stretching sheet in the presence of non-linear thermal radiation, variable thermal conductivity and different nanoparticles shapes (Bricks, Cylinders, Platelets and Blades) are investigated. H 2 O is used as a base fluid. The governing equations have been solved with Runge-Kutta Fehlberg numerical method. The impact of different parameters on the profiles of velocity and tem- perature in prescribe heat flux (PHF case) and prescribe surface temperature (PST case) is analyzed. Hartman number enhancement has led to the velocity reduction due to the Lorentz force. The temperature has also been increased as a result of Hartman number enhancement because of the Joule heating effect. The rise in the amount of shape factors has caused increases the thickness of thermal boundary layer and local Nusselt number in (PHF case).
