摘　　要：结霜是影响蓄冷板换热性能的关键因素之一,分析导致蓄冷板表面结霜的因素有利于对结霜过程的理解。采用计算流体力学(CFD)方法对蓄冷板表面结霜过程建模。基于建立的蓄冷板强制通风二维模型,分析蓄冷剂相变温度、入口风速对蓄冷板换热效果的影响,并提出了结霜量减小的优化策略。结果表明,实验值与计算值吻合较好,验证了模型的有效性。Frost formation is one of the key factors affecting the heat transfer performance of the cold storage plate,and analyzing the influencing factors for frost formation on the surface of the cold storage plate is helpful for students to understand the frost formation process and improve their learning efficiency.In this paper,the computational fluid dynamics(CFD)method is used to simulate the frost formation process on the surface of the cold storage plate under different working conditions,and the visualization of the frost formation process of the cold storage plate is introduced from the aspects of modeling,boundary condition setting,model solution and result analysis.Based on the established two-dimensional model of convection heat transfer of the cold storage plate,the frost growth process on the surface of the cold storage plate under different working conditions(including phase-changed material(PCM)phase change temperature and inlet velocity)is numerically simulated.The influence of factors such as the PCM phase change temperature and inlet velocity on the heat transfer performance of the cold storage plate is analyzed,and some optimization strategies for frost growth inhibition frost formation are proposed.The results from this research are helpful for improving the understanding of professional knowledge and the ability to solve practical problems with simulation methods for students.
