Numerical simulation of entropy generation for nanofluid with the consequences of thermal radiation and Cattaneo-Christov heat flux model

Nanofluids have attracted a lot of attention as a result of their various manufacturing, technical, and medical purposes. The current investigation looks at the usage of Casson nanofluid in a permeable solar collector flow on an indefinite surface. Copper oxide-water (CuO H2O), titanium dioxide-water (TiO H2O), and disulfide molybdenum-water (MoS4 H2O) nanofluids outcomes were all evaluated and expounded on as well. Copper oxide (CuO) nanoparticles have more elevated heat conductivity than titanium dioxide (TiO) nanoparticles, the Copper oxide-water (CuO H2O) nanofluid demonstrated better heat transport capability than titanium dioxidewater (TiO2 H2O) nanofluid. As the values of various parameters improve, the velocity, temperature, and entropy profiles of specified fluids grow and decrease, as shown in the graphical depictions. Using appropriate similarity adjustments, the governing partial differential equations were converted into nonlinear ordinary differential equations. The shooting technique is used in conjunction with the MATLAB software included with the bvp4c to compute a highly nonlinear system of equations. Graphs show the effects of key factors on velocity and temperature concentration. The temperature profile rises as shape factors rise. The temperature panel is decreasing as the Cattaneo-Christov component increases. By increasing the influence of the Biot number, both temperature and entropy profiles are rising. The conclusions for Casson nanofluid are analyzed using the parameterized development of the Cattaneo-Christov component. These findings are helpful for the thermic control of heat transmission in upcoming technologies. Finally, the dynamics of fluid flow are investigated using streamlines.

Automated summary

Nanofluids have been widely studied due to their various manufacturing, technical, and medical purposes. This investigation examines the use of Casson nanofluid in a permeable solar collector flow and evaluates the outcomes of copper oxide-water, titanium dioxide-water, and disulfide molybdenum-water nanofluids. It is found that copper oxide-water nanofluid exhibits better heat transport capability compared to titanium dioxide-water nanofluid. The study also analyzes the effects of various parameters on the velocity, temperature, and entropy profiles of the fluids.
