Maximizing thermal efficiency of a cavity using hybrid nanofluid

Background:
Increasing population growth and economic progress are partially to blame for the global issue of climate change and rising energy usage. One important step towards dealing with this issue would be to enhance the efficiency of a thermal system using tiny nanoparticles. Adding hybrid nanoparticles in a working fluid results in a “hybrid nanofluid” which can improve the efficiency of a thermal system to meet the rising demand for energy for current technology.

Aim:
This study aims to increase the heat transfer in an inclined cavity using Agsingle bondTiO2 nanoparticles. The novel aspects of this research include evaluating the thermal performance of the suggested thermal system in the presence of a magnetic field and thermal radiation. Moreover, the heat transfer ability of a regular fluid, nanofluid, and hybrid nanofluid will also be compared with each other.

Methodology:
The finite difference method is used to obtain the numerical solutions. The computations are done using MATLAB software.

Findings:
The findings show that the applied magnetic field boosts the heat transfer capacity of nanoparticles. The heat transfer of the fluid increased by 1.6% and 2.5% on adding 4% vol. of TiO2 and Agsingle bondTiO2 nanoparticles, respectively.
