Abstract

High heat flux at reduced wall super heat temperature difference is a major concern of researcher in the area of pool boiling heat transfer. One of the techniques is the use of nanoparticles in base fluid which provides high heat flux at relatively low super heat value. Current investigation concentrates on the impact of TiO₂-water based nanofluids on the wall super heat, boiling heat transfer coefficient, and heat flux at atmospheric pressure. Experimental setup was validated by nucleate pool boiling of distilled water and by retracing the Pioro correlation. Two different concentrations of 12% and 15% by weight of TiO₂ in water as base fluid were tested and on average, enhancements in boiling heat transfer coefficient (W/m² K) were found to be 1.38 and 1.24 for 15% TiO₂ and 12% TiO₂ nanofluids respectively, when compared to the results of distilled water.
