Computational Analysis of Convective Heat Transfer in Ternary Nanofluid (Al2O3

The main objective of this study is to develop a two-dimensional mathematical model to understand the heat transfer phenomenon across a stretched surface in a ternary hybrid nanofluid. A ternary hybrid nanofluid, also known as a tri-hybrid nanofluid, consists of three different types of nanoparticles dispersed within a base fluid, resulting in a complex and advanced type of nanofluid. Al2O3-CuO-TiO2-H2O combination is formed in this study by dispersing the nanoparticles of Al2O3, CuO and TiO2 into water. This mixture helps to cool other appliances, break down hazardous contaminants, and purify the surroundings. The impact of temperaturedependent viscosity as well as viscous dissipation are discussed. Nonlinear ordinary differential equations are created from governing PDE utilizing similarity transformations. In MATLAB software, bvp4c method can then be used to solve these transformed equations.In this study,incorported viscous dissipation terms into the energy IP: 203.8.109.10 On: Sat, 11 Jan 2025 06:58:59 equations, and the effects of radiation were accurately addressed using the Rosseland approximation. The Delivered by Ingenta study also takes into account the impact of nanoparticles, specifically Al2O3, CuO and TiO2. Key parameters have been extensively illustrated in graphical form for clarity and better understanding. A detailed analysis and discussion are provided of the effects of distinct parameters on the temperature as well as velocity profiles. This work is novel in that it modifies the momentum equation by including variable viscosity in conjunction with natural convection and viscous dissipation in the energy equation.
