本研究的目的是发展一个简单的实验和数值方法来研究冻结液滴的温度转变。一个实验方法和几个数值方法进行了探讨。对于实验方法，将液滴悬浮在热电偶连接处的冷空气流中。液滴的温度转变能够被准确地测量并且液滴的冻结被观察到。所建立的数值模型能够预测液滴的温度转变和冻结时间。在数值方法中，一个简单的热平衡模型被确定为预测液滴冻结时间的准确手段。(C)2002爱思唯尔科技有限公司版权所有。
The objective of this study was to develop a simple experimental and numerical method to study the temperature transition of freezing droplets. One experimental approach and several numerical methods were explored. For the experimental method, a droplet was suspended in a cold air stream from the junction of a thermocouple. The droplet's temperature transition was able to be accurately measured and the freezing of the droplet observed. The numerical models developed were able to predict the temperature transition and the freezing time of the droplet. Of the numerical methods, a simple heat balance model was determined to be an accurate means of predicting the freezing time of the droplet. (C) 2002 Elsevier Science Ltd. All rights reserved.
