| 摘 要： | 运用光学干涉诊断方法实时观测NaClO3晶体生长过程，得到晶体生长过程中溶液浓度，晶体尺寸等物理参量．将这些参量与数值模拟得到的结果进行比对，研究重力条件下NaClO3晶体溶液生长过程中速度场、浓度场的分布与演化，尝试提出符合实际情况的晶体生长理论模型,对比两种方法得到的浓度边界层厚度，数值模拟得到了与实验数据相一致的结论.

| Abstract: | Both a real time optical interferometric experiment and a numerical simulation of two-dimension non-steady state model were employed to study the growth process of aqueous NaClO3 crystals. The parameters such as solution concentration distribution, crystal dimensions, growth rate and velocity field were obtained by both experiment and numerical simulation. The influence of earth gravity during crystal growth process was analyzed. A reasonable theory model corresponding to the present experiment is advanced, The thickness of concentration boundary layer was investigated especially. The results from the experiment and numerical simulation match well. |
