摘　　要：利用 FLUENT 对太阳能融雪系统路面冰雪融化过程进行数值模拟,得出路面融雪的温度场及相界面移动规律。对系统参数的选择进行分析,得出融雪所需时间与影响太阳能融雪系统工作特性的一些参数(外界环境条件、管径、埋管深度、管间距)的关系。所得结论对太阳能一土壤蓄热融雪系统路面部分的设计以及优化有重要的参考价值。The process of snow melting on pavements has been simulated by using a commercial CFD software FLUENT. Temperature fields of soil and snow were obtained. The propagation of the phase interface was also calculated. At the same time, the relationship between melting time and the geometry parameters such as diameter, pitch and depth of the pipe in different environmental conditions were acquired. The results can be considered as basic references for the design and optimization of the solar-hydronic snow-melting system.
