Boiling heat transfer has maintained a high degree of interest due to the range of its applications in the energy sector. In recent years, much research has focused on improving the nucleate pool boiling by modifying the fluid properties. In this review article, the basic properties and characteristics of Al2O3 nanofluids and few other nanofluids are explored and discussed through past research findings. Next, previous studies that involved pool boiling heat transfer enhancement using Al2O3 nanofluid and its performance in terms of critical heat flux (CHF) and heat transfer coefficient (HTC) are further highlighted. These studies have employed methods that affected the performance of CHF and HTC such as electric field and surface modification. Maximum enhancement in CHF measured is approximately 200%. On the other hand, usage of prediction models to predict enhancements are also discussed thoroughly. Regardless of boiling performance enhancements with the deployment of nanofluids, several concerns must first be addressed before it is able to be deployed for practical use.

“…Due to its high heat transfer coefficient, boiling heat transfer (BHT) has been used widely in heat removal and thermal management applications, such as nuclear power, solar power, electronic chip cooling, and refrigeration. − However, the physics of boiling is complex and involves multiscale processes, phase changes, interfacial interactions, and bubble growth and departure. To demonstrate BHT performance, researchers developed the well-known boiling curve. , Two important factors are used to evaluate heat transfer performance: the heat transfer coefficient (HTC), which indicates the heat transfer efficiency, and critical heat flux (CHF), which represents the heat removal capacity limitation. , Much effort has been devoted to enhancing heat transfer performance by, for instance, modifying the properties of the working fluids, − changing the heating surface character, − and introducing an external force for active regulation. − …”

The wettability of a heating surface has a significant effect on boiling heat transfer (BHT). However, the requirements of the boiling process for surface wettability under different superheat levels change dynamically, and static wettability cannot meet this dynamic demand. Hence, based on the Rohsenow correlation and Kandlikar correlation, the best corresponding relationship between temperature and wettability was found, and a smart wettability-regulating surface with wettability varying with superheat was designed. The smart surface can easily nucleate at low superheat and has a high BHT coefficient, similar to the hydrophobic surface. Moreover, it can gradually delay the arrival of the critical heat flux as the wall superheat increases. The critical heat flux of the smart surface was the same as that of a hydrophilic surface and was 19.8% higher than that of a hydrophobic surface. It had the highest total BHT capacity, 13% better than that of a hydrophobic surface.
