Entropy and thermal dynamics motivated by ternary nanocomposites and geometric influence of oblique channel

Thermal transport in converging/diverging channels finds applications in various engineering fields, including heat exchangers, microfluidics, and biomedical devices, due to their ability to enhance heat transfer and control fluid flow. The use of nanoparticles cannot be circumvented because of their promising characteristics. These materials widely used in applied thermal engineering, to enhance or control thermal transport in machinery, transformer, chemical engineering. The flow in tank designed for oblique walls is common in practical situations and the dynamics of fluids are essential to maintain it for desired purposes. Therefore, the concept of traditional nanoliquid models is extended for advanced ternary fluids. To acquire the beneficial model results, the momentum slip, viscous dissipative phenomena and elastic walls conditions along with new innovative ternary nanoliquid characteristics are adopted for the model formulation. Then, the results with special emphasis on thermal, entropy optimization, shear drag and heat transport rate are obtained via RK scheme and a comprehensive physical description is provided. The ternary nanoliquid possesses remarkable thermal transport and dominant behaviour is inspected for entropy, shear drag and heat transfer rate at the elastic walls under [Formula: see text] and γ. These fluids are recommended for different application especially in applied thermal engineering.
