在水平矩形通道内进行了过冷水的强制对流沸腾实验。实验是针对长度为10、20或40 mm的加热表面进行的。在过冷过渡沸腾中观察到了微泡沸腾现象，且受热面越短，微泡沸腾越容易发生。在较高的过冷水流速下，甚至在较低的过冷度下也会产生MEB。在较高的过冷度和较高的水流速下，都观察到了风暴式的MEB。在强风暴的MEB中，热流迅速上升到临界热流以上，伴随着较大的噪声和振动。© 2001 Scripta Technica，Heat Trans Asian Res，30（5）：426-438，2001
Forced convection boiling of subcooled water was performed in a horizontal rectangular channel with the heated surface on the bottom. The experiment was conducted for heating surfaces, 10, 20, or 40 mm in length. Microbubble emission boiling (MEB) was observed in subcooled transition boiling and was easy to generate for the shorter heating surfaces. In higher flow velocity of subcooled water, MEB was generated at even lower subcooling. Stormy MEB was observed at both the higher subcooling and the higher flow velocity of water. In the stormy MEB, the heat flux rose rapidly above the critical heat flux with larger acoustic noise and vibration. © 2001 Scripta Technica, Heat Trans Asian Res, 30(5): 426–438, 2001
