Significance of radiated ternary nanofluid for thermal transport in stagnation point flow using thermal slip and dissipation function

Abstract

Investigation of heat transfer is a potential research area to acquire the targets in engineering and various industries. Although, conventional liquids are good for many such applications but their heat transfer rate is limited and thus it is essential to study new fluids which meet the requirements. Therefore, a new ternary nanofluid model acquired using enhanced thermal conductivity, electrical conductivity, heat capacity, basic governing laws and similarity transforms. The model comprises the motivational aspects of thermal slip, convective condition, radiative flux and viscous dissipation and predict the parametric ranges for excellent heat transfer results. The nanoparticles (Al2O3, CuO and Cu) amount is kept up to 0.04. For the results simulation, the numerical technique based on shooting scheme is implemented and solved the model. It is scrutinized that induction of aforementioned physical quantities significantly improved thermal transport performance of ternary nanoliquid. These are an excellent sources to acquire the preferred amount of heat for industrial applications. Further, higher B1 near surface boosted the temperature with increasing B1 in the range of 0.1–0.4. The heat transfer rate at the surface effectively enhanced for thermal slip (α1), radiation number (Rd) and Biot number (B1) in the range of 0.1,0.3,0.5,0.7.
