摘要

In the paper, an experimental work examining the impact of beta Ga2O3/water nanofluid turbulent flow through a microscale backward-facing step has been conducted. The Reynolds number range of 5,000 to 10,000 has been applied. Numerical simulation was conducted to validate the current experimental study. The results indicated a significant increase in the Nusselt number compared to the base fluid. However, increasing the volume fraction led to an increase in the friction factor. Moreover, the pumping power has been increased due to the pressure drop increases. As a result, performance evaluation criteria have been established for evaluating the thermal performance of beta Ga2O3/water.
