Enhancing heat transfer is vital due to the limitations of conventional fluids such as water. Hybrid nanofluids, formed by mixing two types of nanoparticles within a base fluid, exhibit improved thermal efficiency. This research investigates how the volume fraction of hybrid nanoparticles in water and ethylene glycol is affected by a magnetic field in a cavity with horizontally moving walls. Key aspects include nanoparticle volume fraction, Reynolds number, Hartmann number, and Richardson number. The findings show that ethylene glycol enhances heat transfer by 15 to 86% compared to water, while increasing the volume fraction of hybrid nanofluids can lead to a heat transfer improvement of 20 to 235%. A higher Reynolds number promotes convective flow, improving heat transfer by 90 to 274%. In contrast, raising the Hartmann number and Richardson number diminishes heat transfer, resulting in reductions of 45 to 97% and 35 to 86%, respectively.
