研究了瞬态加热模式下小受热面上核态沸腾向微泡喷射沸腾的转变。在临界热流密度后壁温迅速升高的短暂不稳定沸腾过程中，在过冷度为30-40 K的汽膜上观察到毛细波。在此过程中的可视化结果表明，部分崩溃的蒸汽膜诱导强烈的射流向加热表面，因此避免了完全干燥。这一机制在MEB向稳定的过渡过程中发挥了重要作用。进一步比较了壁温与沸腾状态的关系，发现稳定MEB起始点的壁温取决于过渡过程中MEB模式对膜沸腾的优势。同时研究了过冷度和表面氧化对相变过程的影响。
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.
