摘要
利用近似分析求解的方法解决有限区域多相变问题存在很大的困难,一般只能用数值分析方法来处理。为了解决螺旋盘管相变热传导求解困难的问题,建立相变材料数学模型,并利用Fluent软件对螺旋盘管相变换热器蓄放热过程进行数值仿真,获得装置内PCM的温度场、液相分数及速度场分布状况。
At present, it is very difficult to solve limited multiphase change problem by use of approximate analytical solution methods, and numerical analysis method is generally only used. In order to solve the difficult problem of spiral coil PCM , it has established a mathematical model of PCM, and the simulation research about exothermic process of spiral coil PCM heat exchanger based on fluent was conducted. It ob- tained temperature, liquid fraction and velocity distribution situations of PCM within the device and the simulation results provide a theoretical reference for the heat exchanger design and product development.
