摘　　要：通过对低温储存粮食用水蓄冷式装置的数值模拟,分析了蓄冷过程中的斜温层变化特征与温度场的分布特性,定量评估了不同参数(高径比、布水器出口数量)下蓄冷装置的蓄冷效能,为粮食低温储存设施建设的改进提供了可行的优化思路。Based on the numerical simulation of chilled water storage system for the storage of grain,thermocline and the distribution of the temperature during the cooling energy storage are analyzed.The efficiency influenced by different parameters,such as ratio of height to diameter,and number and shape of the water distributor outlets,is evaluated quantitatively.An optimization for the improvement of low-temperature grain storage facilities is feasible according to the simulation results.
