“…We note that the maximum heat flux is not the CHF because the experiment was intentionally stopped at this point to avoid burning of the silicone sealing. These results correspond to those of a previous study that included the MEB regime (Zhu et al, 2014). Using the same setup, subcooled pool boiling tests were carried out for different gap heights.…”

“…Different from fully developed nucleate boiling and MEB, a vapor film covers most of the heating surface during the transition process and restrains the surrounding liquid reaching the heating surface, as shown in Figure . This behavior is much more similar to that in film boiling on a small heater under saturation and low liquid subcooling conditions . Ono and Sakashita deemed that the rapid increase in wall temperature for subcooled boiling on a small copper heater was arisen from the depletion of the liquid macrolayer underneath the vapor film.…”

This study investigated the transition from nucleate boiling to microbubble emission boiling (MEB) on a small heating surface under transient heating modes. During the short unstable boiling process after critical heat flux with a rapid increase in wall temperature, capillary waves were observed over the vapor film at subcooling of 30–40 K. The visualization results in this process demonstrated that the partial collapse of vapor film induced strong jet toward the heating surface and therefore avoided complete dryout thereon. This mechanism certainly plays an important role in the transition to stable MEB. Further comparison between the wall temperature and boiling states indicates that the wall temperature at onset point of stable MEB is determined by the predominance of MEB mode over film boiling in the transition process. Effects of liquid subcooling and surface oxidation on the transition process were also investigated at the same time.
