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

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. Pervi-ousness, 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 trans-ferring facets of Cu - TiO2 in the flow are inspected using the most important parameters. Thermal jump con-ditions 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.

Automated summary

This study investigates the heat-transferring properties of engine oil with MHD effects using Ellis nanofluid, which contains copper (Cu) and Titanium oxide (TiO2) nanoparticles. The movement of engine oil is influenced by the presence of Cu and TiO2. Various factors such as viscous dissipation, thermal radiation, heat flux model, joule heating, and heat generation affect the energy equation. Mathematical representations are used to describe permeability, entropy creation, and a flat moving surface with non-uniform elongating velocity. The numerical technique bvp4c is employed to solve complex differential equations and analyze the flow and heat-transferring facets of Cu-TiO2. The study concludes that temperature and heat transfer rate decrease due to certain limitations, but these fluids can be used with caution in applications requiring heat transfer control. The findings contribute to the understanding of engine and generator cooling systems, aircraft refrigeration systems, nuclear cooling systems, and other technologies.
