Energy and mass transmission through hybrid nanofluid flow passing over a spinning sphere with magnetic effect and heat source/sink

Abstract

Thermophoretic particle deposition (TPD) and thermal radiation have significant uses in engineering and research, such as projectiles, electrical fuel, and production of coating sheets, thermal transference, nuclear plants, renewable energy, aerospace engineering, and gas turbines. In light of the above applications, the present analysis examines the stagnation point flow of hybrid nanofluid (hnf) around a revolving sphere. The hnf is prepared with the addition of Cu and Al2O3 nanoparticles in the water. The flow is examined under the impact of chemical reaction, thermal radiation, TPD, and activation energy. The flow equations are reformed into a dimensionless set of ordinary differential equations and then solved through the numerical approach parametric continuation method. The graphical and numerical results are demonstrated through graphics and tables. It has been noted that the effects of acceleration and rotational parameters boost the hnf (Cu and Al2O3/water) velocity. Furthermore, the energy outline reduces with the effect of acceleration parameter and nanoparticle volume friction. The influence of the rotation factor and acceleration parameters boosts the rate of skin friction. The influence of thermal radiation enriches the energy transmission rate.
