Thermal decomposition of hybrid nanofluid confined by radiated curved stagnated surface capturing partial slip effects

Abstract

Thermal aspects of hybrid nanofluid are more special owing to enhanced thermal performances. Such improved thermal characteristics makes the hybrid nanomaterials productive with applications of solar systems, heating of engineering devices, cooling phenomenon, energy production etc. Following to such attentive applications in mind, this continuation aims to reflects the comparative thermal efficiencies of hybrid nanofluid model with nonlinear radiative phenomenon due to curved surface. Two famous types of nanoparticles namely alumina oxide (Al2O3) and copper (Cu) are taken as hybrid nanoparticles. The oblique stagnated flow due to curved radiative surface is accounted for the curved configuration. The flow pattern is inspected with implementation of velocity and thermal slip conditions at the boundary. Non-linear partial differential equations are transmuted into non-linear ordinary differential equations through the use of similarity transformations. The Keller-Box technique, which is a well-known method, is utilized to obtain the numerical results. Furthermore, the impact of slip parameters, velocity ratio parameters, Prandtl number, non-uniform heat source and sink parameters, radiation parameter, stream lines, heat transportation rate along with skin-friction on thermal and velocity distributions are examined and depicted via graphs and tables. It is observed that temperature profile enhanced due to velocity ratio parameter and curvature constant. The improvement in heat transfer is more impressive for nonlinear radiative phenomenon as compared to linear thermal radiation consideration. Furthermore, a control of heat transfer pattern is observed due to interaction of thermal slip effects.
