Abstract: This category of liquids is in high demand because of the substantial increase in thermal efficiency as well as other nano fluid properties. During this study, the numerical assessment of nano fluids, such as CuO and ZnO, is considered to explore the nucleate boiling phenomenon. Critical improvement of the heat flux during the boiling of the adopted nano fluids at specific VOF levels has been visualized. Computational findings show that thermal properties of nano fluids such as heat transfer coefficient, surface heat flux, bubble frequency increase with the maximum concentration of nano fluids. The results show a similar trend with the literature. ZnO nano fluid delivers better results after a time period of 1 s, especially in comparison to CuO and other nano fluids due to higher thermal conductivity.
