A numerical approach for MHD Al₂O₃–TiO₂/H₂O hybrid nanofluids over a stretching cylinder under the impact of shape factor

Abstract

In this research, the heat transfer and magnetohydrodynamic stagnation point flow of a (Al 2 O 3 -TiO 2 /H 2 O) hybrid nanofluid past a stretching cylinder under the impact of heat generation, nonlinear thermal radiation, and nanoparticles shape factor has been analyzed using the Runge-Kutta-Fehlberg fifth order numerically method. The impact of changing diverse parameters, such as nanoparticles shape factor, named hexahedron and lamina, on temperature and velocity profiles and induced magnetic field, has been explored. The main motivation of this article is using hybrid nanoparticles to improve heat transfer. The novel findings of the current research illustrate that the Lorentz force produced by increasing magnetic field parameter (M) causes a decline in velocity profile; also increasing solar radiation, shape factor and the use of hybrid nanoparticles caused increment in the temperature profile. Furthermore, the lamina nanoparticle shape has more impact on Nusselt number (Nu) compared with hexahedron-shaped nanoparticle.
