Entropy generation analysis of magnetized radiative Ellis (Cu-TiO2/Engine Oil) nanofluid flow using Cattaneo-Christov heat flux model with viscous dissipation and Joule heating effects

Abstract

The most recent research looks into the heat-transferring assets of engine oil based on Ellis nanofluid with MHD effects, which contains nanoparticles of copper (Cu) and Titanium oxide (TiO2). The concert of Copper (Cu) and Titanium oxide (TiO2) was seen in the movement of engine oil. Viscous dissipation, thermal radiation, the Cattaneo-Christov heat flux model, joule heating, and heat generation all change the energy equation. Perviousness, entropy creation, and a horizontally flat moving surface with a non-uniform elongating velocity are all represented mathematically in the model. To locate the numerical explanations of the problem, bvp4c, a convincing numerical technique for solving complex differential equations, is used. The flow and heat transferring facets of Cu-TiO2 in the flow are inspected using the most important parameters. Thermal jump conditions and absorbent media have a momentous impact on flow. It is noted that the temperature and heat transferring rate are reduced as a result of the involvement of important limitations. However, such fluids should be employed in controlled volume as caution in applications requiring heat transfer control. Concluding the recent effort will help in studying engine and generator cooling systems, aircraft refrigeration systems, nuclear cooling system, and other technologies.
