A subcooled pool boiling has been performed for the purpose of developing high heat flux cooling technology. Microbubble emission boiling (MEB) has occurred for a mixture of anti-freezing liquid and water. The heat flux increases higher than the critical heat flux (CHF). In the boiling of water under the pressurized condition of 0.1MPa in gage for an example, MEB occurs and the heat flux increases higher than the CHF. In subcooled flow boiling in a microchannel, the vapor fills whole of the channel and the boiling turns to film boiling. These experimental results give effective information for the practical cooling technology.In subcooled pool boiling of water in an acoustic field, MEB has been observed at frequency of 500Hz. According to the PIV analysis of microbubbles in MEB, the subcooled liquid has been observed to flow into the heating surface. The experimental results give the mechanism of MEB and solid-liquid contact.

为了开发高热通量冷却技术，进行了过冷池沸腾。防冻液和水的混合物发生微泡发射沸腾（MEB）。热通量增加至高于临界热通量 (CHF)。以表压0.1MPa的加压条件下的水沸腾为例，会发生MEB，并且热通量增加得高于CHF。在微通道内的过冷流沸腾中，蒸汽充满整个通道，沸腾转变为薄膜沸腾。这些实验结果为实际冷却技术提供了有效的信息。在声场过冷池水沸腾中，在500Hz频率下观察到MEB。根据MEB中微泡的PIV分析，观察到过冷液体流入加热表面。实验结果给出了MEB和固液接触的机理。
