Numerical Study on Mixed Convection Stagnation-Point Flow of Reiner-Philippoff Hybrid Nanofluid over a Shrinking Sheet

Abstract

This study introduces a mathematical model that addresses the mixed convection stagnation point flow of a non-Newtonian Reiner-Philippoff hybrid nanofluid over a shrinking sheet. Through the application of theoretical assumptions, the governing equations were formulated and subsequently simplified into a set of ordinary differential equations (ODEs). The model facilitates the computation of steady flow solutions utilizing the MATLAB software function bvp4c. The primary objectives of this research include an analysis of the effects of various parameters on flow dynamics and thermal behaviour. These parameters encompass the mixed convection parameter, the solid volume fraction of nanoparticles, and the mass flux parameter, all of which significantly influence flow characteristics. Numerical results have been obtained for critical metrics, including the skin friction coefficient, local Nusselt number, and the velocity and temperature profiles. The findings contribute to a deeper understanding of hybrid nanofluid behaviour in thermal management applications, offering valuable insights for future research endeavours in the domains of fluid dynamics and heat transfer.
