Thermal enhancement in buoyancy-driven stagnation point flow of ternary hybrid nanofluid over vertically oriented permeable cylinder integrated by nonlinear thermal radiations

Abstract

Enhanced heat transport in advanced nanofluids (ternary hybrid nanofluids) is one of the major demands of the time and is potentially contributing in food processing to maintain the temperature of building, cooling of electronic devices, paint industries and biomedical engineering. Therefore, an efficient heat transport model is developed in this study and innovative ternary mixture [(Al2O3-CuO-Ag)] along with feasible thermophysical attributes comprising the effects of ternary nanoparticles and similarity equations are exercised to obtain the desired sort of nanoliquid model. This model is related to vertically oriented cylinder with novel upgradation of permeability, upthrust forces and nonlinear solar thermal radiations. In the next stage, mathematical treatment of [(Al2O3-CuO-Ag)/H2O]thnf is done and successfully achieved the desired convergence and then organized the graphical results. The furnished results disclosed that tri-composites-based nanofluid has low velocity than hybrid and common nanofluids. Moreover, temperature in [(Al2O3-CuO-Ag)/H2O]thnf is dominant over both hybrid and mono nanofluids. The integrated effects of nonlinear thermal radiations are of much interest in the temperature enhancement and observed that Rd and [Formula: see text] are better for thermal improvement.
