HEAT TRANSFER ENHANCEMENT BY INTEGRATING BUBBLE RISING IN GRAPHENE OXIDE (GO)-WATER NANOFLUID

Rising gas bubbles in a liquid improve heat transfer by inducing vortices that enhance fluid mixing. Alternatively, nanofluids enhance heat transfer by dispersing thermally conductive nanoparticles in a base fluid, increasing its effective thermal conductivity. This study investigated the combined effects of rising air bubbles in GO-water nanofluid to evaluate their synergistic impact on heat transfer enhancement. With the integration of these two techniques, heat transfer was improved by up to 163% compared to the control case. The success of this research opens new opportunities in various cooling systems, such as immersive cooling, solar panel cooling and heat exchangers.
