| 摘 要： | 通过分析影响沸腾的各种因素,结合水的流动特性以及激光在水中按照指数衰减的特点,利用单元差分方法着重分析了整个光斑所在区域过余温度的分布,借助水沸腾状态与过余温度之间的关系,建立了水在激光作用下的强制流动沸腾模型.环行光束被作为主要研究对象,对环行光束进行了数据模拟和实验验证.在实验中采用照相法记录下气团的形态,与模拟沸腾曲线具有较好的一致性.

| Abstract: | Various factors affecting boiling state are analyzed when water flow and exponent-decadence of laser by water characteristic are considered. By using unit difference methods surplus temperature of the coverage by laser is studied. According to the relationship of surplus temperature and boiling state, forced Convective Boiling modal of water by laser is founded. Annular beam is regarded as the main research object, concerned data was simulated and experiments are carride out. As a result they have good coherence. |
