太阳能相变储能水箱释能性能的数值模拟
Numerical analysis of the discharging performance of a solar energy storage tank containing PCM modules
摘要
Abstract
Numerical simulations were carried out on the discharging behaviour of a thermal energy storage water tank containing PCM modules and a tank containing only water. The modeling was done by using a CFD software package FLUENT. The results show that the cold inlet water can be heated by the PCM module during the discharging process and the PCM modules also act as a diffuser to reduce the disturbance caused by the inlet cold water. The PCM modules improve the thermal stratification of water during the discharging process. At a flow rate of 5 L/min, the discharging efficiency of the tank with PCM modules is 7% higher than that of the normal tank and the discharging efficiency of the water tank with PCM modules decreases with increasing water flow rate.关键词
