摘要
以蒸汽分子扩散模型为基础,建立了预测霜层生长过程的数学模型,并建立了以液氮为冷媒的管内强制流动结霜实验台.由数值计算预测的结霜参数如霜层厚度等与实验数据符合较好.
Based on molecular diffusion model of water vapor a theoretical model of frost growth is established and an experimental set with a liquid nitrogen cooled tube is built up. By numerical method, the predicted parameters, such as thickness of frost,well agree with the experimental data.
