“…Li and Liang , found that the pressurizing time interval and the pressurizing gas consumption were decreased in the LH 2 tank while the raising of inlet temperature from 258 to 298 K and inlet mass flow rate from 1.06 to 4.24 g/s. However, it is still recommended to simulate the aerospace cryogenic storage tank under varied gravity and microgravity conditions. , Li et al found that the cryogenic jet with a higher incident mass flow rate of 0.14 kg/s or using the cryogenic jet injection earlier when the tank filling ratio is high can prevent the development of thermal stratification in the large-scale model tank under microgravity conditions. Wang et al found that noncondensable helium gas was advantageous for pressure management in the LH 2 tank with successively varied gravity as the helium could restrain the pressure minimum limit in the depressurization stage.…”

Phase change is a phenomenon that has been extensively utilized in chemical engineering, energy, electronics, vehicle, and space exploration. From both the science and engineering perspectives, gaining a profound understanding of the intricacies of multiphase flow processes accompanied by heat and mass transfer due to phase change is of fundamental importance. Indeed, the computational fluid dynamics (CFD) has been increasingly applied as an effective tool to give an in-depth and efficient analysis of the phase change processes, thereby enhancing our understanding and capacity to control and optimize the phase change effects in these processes. This paper seeks to provide a comprehensive review of the utilization of CFD methodologies in the simulations of phase change flows across various applications, including temperature management, drying, separation and purification, and others. First, the CFD models at various scales that are developed to elucidate the phase change processes are summarized. Second, the noteworthy advances in the recent CFD simulation work on various phase change processes are presented, respectively. Finally, the challenges and potential prospects to facilitate the application of the phase change flow are discussed. The current review aims to offer insightful guidance for the CFD modeling of phase change processes in numerous engineering application scenarios.
