“…In quenching processes, the subcooled liquid directly contacts a hot surface of solid objects, and fast boiling occurs to remove the heat from substrates. Ramezanzadeh et al simulated the cooling rate and temperature uniformity of a steel plate in the jet impingement quenching process. It recommended that two pulsating jets with a step period equal to 1 s, each jet frequency of 5 Hz and amplitude 1 can reduce the temperature uniformity index by up to 67%.…”

“…However, these assumptions need to be improved if the thermal field at the solid wall is essential, such as microchannels analysis with the solid wall being massive in comparison to the flow field and microscale bubble nucleation analysis . The conjugate heat transfer method can be used to obtain more realistic distributions of the temperature, heat flux, and heat transfer coefficient for solid surfaces. , The energy equation of the solid wall is solved with the conjugate heat transfer method ( d false( ρ s C p , s T false) d t = ∇ · false( k s ∇ T false) + Q s o u r ) . Moreover, the nucleation site and contact line evaporation can also be resolved in numerical simulations with conjugate heat transfer analysis.…”

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.
