Numerical simulation analysis of icing process in ice model tank

[目的]为研究冰水池结冰的特征和影响因素,对冰池水结冰过程开展数值模拟分析。[方法]采用计算流体力学软件FLUENT中的流体体积法(VoF)两相流模型,建立冰水池数值模型,设定热力学边界条件,观察计算域内温度场和冰场的动态变化过程,分析冷气进口设置方案对结冰过程的影响。[结果]研究结果表明,随着冷气进口数量增加,冰水池结冰速率更快,更容易形成均匀的层冰。[结论]结冰过程数值模拟结果揭示了冷气进口数量与结冰之间的关系,可为冰水池控制结冰提供参考。

[Objectives]The icing process in an ice model tank is numerically simulated to study the charac-teristics and influencing factors of icing.[Methods]The volume of fluid(VoF)two-phase flow model in computational fluid dynamics software FLUENT is used to build the numerical model of the tank and set the thermodynamic boundary conditions,in order to observe the dynamic change process of the temperature field and ice surface in the calculation domain,and analyze the influence of the air-conditioning inlet setting scheme on the icing process.[Results]The research results show that as the number of air-conditioning inlets in-creases,the ice model tank freezes faster and it is easier to form a uniform layer of ice.[Conclusions]The numerical simulation results of the icing process reveal the relationship between cold air and icing,which can provide references for controlling icing in ice model tanks.
