| 摘 要： | 移动粒子半隐式（Moving Particle Semi-implicit，MPS）数值方法在追踪汽液相界面上较传统网格方法有很大优势，本研究基于MPS方法对过冷水中单个蒸汽泡的冷凝行为进行了数值模拟研究。计算结果与Kamei的实验结果符合较好并表明，汽泡冷凝寿命与汽泡初始尺寸呈近似线性关系，低过冷度下大汽泡的变形会加...

| Abstract: | Moving Particle Semi-Implicit(MPS) Method has an advantage over traditional meshbased methods in accurately trace the vapor-liquid interface.In this study,we had performed a numerical simulation of single steam bubble condensation behavior.Numerical results showed a good agreement with Kamei's experiments and indicated that there is approximately a linear relationship between bubble initial size and bubble lifetime.A larger bubble condensation process would be accelerated by its deformation at lower degrees... |
