Melting heat transfer features in a Bo¨dewadt flow of hybrid nanofluid (Cu−Al2O3/water) by a stretching stationary disk

Abstract

The melting impacts on the three-dimensional hybrid nanofluid flow by a stationary stretching disk is examined. The flow configuration is due to the stretching of the disk. The magnetic field is applied normal to the disk in order to generate the resistance in the liquid. The performance of heat transfer in the liquid, the thermal radiation and heat generation/absorption impacts are taken into consideration. The melting heat transfer impact on the surface is analyzed here. The impact of stretching and rotating mechanisms along with applied physical impacts on the hybrid nanofluid flow and heat features are of the present concern for this physical problem. A conventional transformation is presented to lead to a set of coupled similarity equations which are highly non-linear in nature. A numerical method subject to bvp4c technique is adopted for the solution process. Results reveal that increasing trend of stretching of the disk lowers the boundary layer thickness and consequently highers the rate of heat transfer. It is found the reduction in thickness of thermal boundary layer by the strength of stretching. Additionally, the temperature distribution rises by the influence of melting temperature. Further, the skin fraction coefficient seen to be enhanced with the enlargement of nanoparticles volume fraction.
