分析和比较了在单组分和双组分体系中，恒定的和与半径相关的平动气泡速度对单个气泡坍缩率的影响。假设势流场或修正势流场的准稳态。在此基础上，尝试分析了微过冷水强制对流表面沸腾过程中气泡上升速度和主流横流的联合效应。所得结果与现有的大部分冷凝过程的实验数据非常吻合。探讨了进一步改进的思路，并提出了分析流场中气泡破裂的一般框架。
The effects of constant and radius-dependent translational bubble velocity on the collapse rate of a single bubble in a single and two-component system, either pure or containing non-condensables, are analysed and compared. A quasi steady-state in a potential or modified potential flow field is assumed.An attempt is then made to analyse the combined effects of bubble rise velocity and main stream cross flow in forced convection surface boiling in slightly subcooled water. The results are in excellent agreement with available experimental data for most of the condensation process. Ideas for farther improvements are explored, and a general framework for analyzing bubble collapse in a flow field has been suggested.
