Abstract:
The high-speed multiphase hydrodynamic processes of high-speed vehicles, such as underwater launching and supercavitation navigation, require consideration of thermal effects on cavitation dynamics during the formation of cavities by the injection of high-temperature gas. Additionally, cavitation phenomena occurring in engineering problems, such as rocket cryogenic liquid fuel supply and high-temperature pipeline transportation in nuclear reactors, also exhibit significant thermal effects. In these flow scenarios, thermal effects not only alter the physical properties of the fluid, affecting interphase mass transport and heat transfer but also trigger complex dynamics and thermodynamic changes. Therefore, understanding the mechanisms of cavitation considering thermal effects, the laws of energy transfer and transport, and the mechanisms of flow instability are critical scientific issues that need to be addressed. This paper categorizes cavitation/cavity flows considering thermal effects into four types based on different influencing factors: high-temperature wall cavitation, high-temperature ventilated cavitation, high-temperature water cavitation, and low-temperature thermally sensitive fluid cavitation. This paper comprehensively reviews the evolution characteristics and influencing laws of four types of cavities. Additionally, the paper summarizes the cavitation models and turbulence models commonly used in numerical simulations considering thermal effects, as well as various multiphysics field measurement techniques employed in experimental studies. However, the related numerical simulation and experimental techniques still need further development and improvement. Future research should delve deeper into the mechanisms by which thermal effects influence the generation and stability of cavitation/cavity flows, to fully understand and master the characteristics and behaviors of cavitation flows with thermal effect, providing more accurate data support, analysis tools, and theoretical foundations for engineering design and optimization in related fields.
