Convergence and stability analysis on the rotating hybrid flow of Cu–Fe2O3/water

Abstract

The consequences of inclined magnetic field, nonlinear thermal radiation, chemical reaction, diffusion-thermo, and thermal-diffusion effects on the rotational flow of electrically conducting Cu–Fe2O3/water hybrid nanofluid past a convectively heated bidirectionally stretching sheet are scrutinized. A comparative test between Type 1 and Type 2 models is accomplished preferring two sets of compatible thermo-physical possessions of hybrid fluid. The highly coupled nonlinear partial differential equations and the corresponding initial-boundary constrains are converted into a dimensionless structure employing the appropriate nondimensional variables. The dimensionless boundary layer equations are tackled by making use of the finite difference method explicitly. As the current numerical procedure is conditionally stable, the relevant criteria for convergence and stability are derived. The numerical results are displayed through graphs in the form of concentration, temperature, and velocity profiles. The consequences characterized by miscellaneous parameters on Nusselt number Nu, skin friction coefficients and the Sherwood number Sh are conferred through tables. The temperature of Type 2 hybrid nanofluid model exceeds that of Type 1 model. The convective parameter improves the rate of heat transfer. The heat transfer rate of Type 1 model is greater than that of Type 2 model. An increase in the aligned magnetic field parameter lowers the Nusselt number.
