The optimisation of heat transfer, which is the transition of thermal energy from regions of high temperature to those of lower temperature, is a cornerstone in the field of thermal sciences and engineering. It is of vital importance to maximise energy efficiency, ensure system performance, and uphold operational reliability across numerous industrial applications. In this context, recent investigations have explored the modification of heat transfer rates through the turbulence induced by air-bubble injections. The technique has found application in heat exchangers, solar stills, and solar collectors, where it can be employed to either augment or attenuate heat transmission. The majority of the research has been dedicated to enhancing thermal efficiency, with both theoretical models and experimental data underpinning our current understanding. This review provides a critical analysis of over 45 studies from the literature, which have examined the implications of air bubble injection across various realms of industry, including heat exchangers, water desalination systems, solar collectors, and diverse media. Our analysis underscores the profound impact of heat transfer rates on process productivity, efficiency, and costeffectiveness across a gamut of applications. A range of industrial processes, such as cooling, heating, evaporation, and condensation, all rely heavily on efficient heat exchange. Enhancements in heat transfer rates hold the potential to curtail energy losses, reduce fuel consumption, and subsequently lower operational costs in industrial applications like solar thermal systems. Moreover, efficient heat transfer is pivotal in minimising temperature variations, thereby contributing to consistent outcomes.
