Abstract

Through the study of ice and water temperature distribution near the interface,a new method of ice detection is found and the theoretical guidance is provided for the research of ice and water transformation.By putting the ice into the water,the ice-water heat transfer have an effect on the water temperature near the interface.Through the study of the temperature distribution,which is 5~9cm、0~4cm、-4~0cm、-5~-9cm to the ice water interface,the fitting section function is got,which named relation function of points from ice and water interface between the distance and temperature.The fitting values and monitoring error is between±0.1~0.3℃.The temperature difference of ice and water interface is bigger;the ice change into water is faster,which is more easily leaded to ice.

利用光纤光栅探测冰与水交界面附近温度场分布的研究

通过对界面附近冰与水温度分布的研究，找到了一种新的冰探测方法，为冰与水转化的研究提供了理论指导。通过将冰放入水中，冰-水传热对界面附近的水温产生影响。通过对距离冰水界面5~9cm、0~4cm、-4~0cm、-5~ 9cm温度分布的研究，得到了拟合截面函数，该函数命名了距离冰水界面点与温度之间的关系函数。拟合值和监测误差在±0.1~0.3℃之间。冰与水界面温差较大，冰变水速度较快，更容易形成冰。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
