Analytic Simulation for Magnetohydrodynamic Unsteady Buongiorno Model Hybrid Nanofluid Flow over Stretching

Abstract

In this work, we inspect and analyze a two dimensional, unsteady mixed convectional hybrid nanofluid hydromagnetic flow (Al2O3-Cu/H2O) over a convectional heated an extending/contracting surface with the influence of thermal radiation. Hybrid nanofluid (Al2O3-Cu/H2O) flows with magnetohydrodynamic and heat source or sink. Brownian motion and thermophoresis were incorporated using the Buongiorno model. Hybrid nanofluid with vol. fraction range limited to 1.5% and within the higher temperature range of 50°C to 70°C is considered for thermal conductivity and viscosity analysis. The proposed model is then converted into ODEs through similarity transformation with the help of homotopy analysis. The effect of embedded input factors on the temperature, velocity, and concentration profiles is visually demonstrated and explained. The magnetic field has inverse impact on velocity and temperature profiles. Velocity profile increases for both mixed convection and buoyancy ratio parameters. It has been noticed that the temperature profile increases with thermal radiation. For increasing values of Lewis number, the concentration of hybrid nanoparticles is considerably lowered. Moreover, we observed an increase in the concentration of hybrid nanoparticles through a destructive chemical reaction, whereas a generative chemical reaction has the reverse effect. It has been proved that skin friction is increasing function of $\epsilon ,M$ and decreasing function of ${\lambda }_1,N_r$ . On the other hand, Nusselt number increased with the increase of $R,Q,N_b,N_t$ while Sherwood number is decreased, with the increase of $N_b,N_t,Le$ .
