Visualization of dynamic phase mixing and equilibrium process in transcritical and supercritical conditions

Critical Threshold for Bubble-like Nucleation during Pseudoboiling at Supercritical Pressures

“…In addition, the GL phase structures including bubble-like and GL film in our MD simulations may have an irregular interface due to the disappearance of surface tension, which is different from the regular bubble during subcritical boiling. At the macroscopic scale, the interface of GL structures may be irregular and blurred. ,, Yang and Chen observed a thick and blurred mixed layer in mixing experiments of LL and GL phase SF, and the boundary between LL and GL phases was difficult to distinguish. In the pulse-heated microwire in sub- and supercritical CO 2 experiments conducted by Wang et al, the boundary layer near the microwire exhibited normal bubbles, unstable gas columns, and blurred garland-like clusters as the fluid pressure increased from subcritical to supercritical.…”
