Boiling is an essential process for many industrial applications such as refrigeration, distillation, chemical processes. The efficiencies of these applications are dependent on effectiveness of the heat transfer processes. This study presents the experimental data analysis for pool boiling performance of 0.10~0.20% (wt%) of Multiwall Carbon Nanotubes (MWCNTs)/water nanofluid on smooth and straight, square and circular grooved surfaces. According to experimental results, the highest enhancement in boiling heat transfer coefficient is observed in configuration S4 consisting of 30mm deep circular groove inclined at 45° angle and 33% higher than the base fluid on the smooth surface. Based on this investigation, the paper indicates that the inclination of the circular groove has the potential to enhance significantly pool boiling heat transfer process. Furthermore, the paper justifies that the effectiveness enhancement analysis of the nanofluids under a range of concentrations and geometrical configurations of heat transfer surfaces is still essential and desirable.
