利用自主研发的CIP-ZJU(Constrained Interpolation Profile Method in Zhejiang University)高精度数学模型研究强非线性自由表面流动问题.模型在直角坐标系统下建立,采用紧致插值曲线CIP方法作为流场的基本求解器,通过多相流的方式实现固-液-气耦合同步求解,采用平衡格式的VOF(VOF/WLIC:Volume of Fluid/Weighted Line Interface Calculation)自由面捕捉方法改进了原模型,利用浸入边界方法处理运动物体.利用改进的CIP模型开展了不同类型的物体冲击液面引起的液滴飞溅现象的数值模拟,重点分析液滴飞溅过程中的自由液面变形、作用荷载和物体位置等.通过数值结果与实验结果的比较验证模型的可靠性.结果表明:平衡格式的VOF自由面捕捉方法能更精确地重构自由面,本文的数学模型可精确预测强非线性自由表面流动问题.

Gas-phase Ca^＋-dipropylamine complex has been subjected to photodissociation （400-690 nm）. One reactive product, Ca^＋-NHC3H7, is detected only in the region of 450-528 nm, besides the evaporation fragment of Ca^＋, which is dominant throughout the whole spectral region we have studied. The photoreaction channel may be explained in terms of a metal insertion mechanism. The calculated results are in good agreement with the experimental observations.
