摘要
提出并证明了利用光纤布拉格光栅(FBG)传感器对水变冰的液固相变过程进行实时监测的可行性,并观测到了该相变过程中的过度冷却现象。在此基础上,展示了基于FBG传感器监测的不同浓度NaCl溶液相变信号,结果显示出了溶液浓度与FBG的相变信号之间的相关性。这种相关性有望提供一种溶液浓度测试新方案。
Abstract
We propose and prove the feasibility that the liquid-solid phase transition of water can be monitored based on FBG sensor. The supercooling phenomenon is observed during the phase transition process. On this basis, we show the phase transition signals of different concentrations of NaCl solution based on FBG sensor monitoring. The results show the correlation between the concentrations and the phase transition signals. This correlation is expected to provide a new scheme of solution concentration testing.
