本文对去离子水在竖直环形小通道内流动过冷沸腾时的气泡行为进行了可视化研究，观察到了气泡在流动沸腾过程中的生长，合并，脱离，滑移及气泡脱离壁面后的运动等现象，并结合气泡动力学理论模型及气泡滑移模型，对实验结果进行了对比分析，总结了本实验通道中气泡行为的特性。
Visualization experiment on bubble behavior of subcooled flow boiling was carried out in a vertical annular channel in this paper. Coalesce, departure, sliding and movie trace of bubbles were observed, and analyzed by bubble dynamics theory. The characteristics of bubble in this experiment were discussed and summarized.
