中文摘要：

为研究烟火药水下燃烧高温残渣与水作用形成的气泡动力学特性,建立了传热、传质数学模型,推导了单个高温残渣气泡的生成模型,计算了生成气泡的半径以及半径的变化率与时间的关系。将计算结果与文献结果进行了比较;并分析了高温颗粒特性对气泡动力学的影响。结果表明,随着时间增加,高温残渣颗粒不断冷却,气泡半径不断增大;但增长速度不断变慢,计算结果与文献结果吻合较好。

英文摘要：

In order to investigate the dynamic characteristics of a bubble induced by the interaction between a hot residue and water from the underwater combustion of pyrotechnic composition,the heat transfer and mass transfer model of a bubble containing a hot residue is established. The bubble radius and its growth rate are calculated,and bubble radius calculated and the literature results were compared,effects of the hot residue characteristics on bubble dynamics are analyzed. Results show that with the high temperature residue continuous cooling,although bubble radius increases constantly,growth rate becomes slowly,and the calculated results agree well with literature.
