Abstract

The study of the laminar, boundary layer, MHD (CuO–Al2O3) hybrid nanofluid flow and heat transfer driven by mixed convection adjacent to a vertical porous plate in the existence of magnetic induction is accounted for. Nonlinear thermal radiations are modeled in order to examine their impacts on energy transport. The influences of conduction-radiation along with magnetic Prandtl number are examined. System of equations that governs the model is simplified using a boundary layer approach along with pertinent dimensionless variables which are further analyzed numerically through a very efficient finite element method. The suitable ambient position is determined through numerical experiments. The convergence is ensured and mesh free analysis is done. Numerical solutions are exposed graphically against assorted parameters for nanofluid as well as hybrid nanofluid and are compared to examine heat transfer characteristics. The induced magnetic field has shown a decreasing behavior when Hartmann and magnetic Reynolds numbers increased.
