对寒冷半干旱地区半地下式马铃薯贮藏室内北墙体温度进行测试分析和模拟研究。试验表明,无论外面天气变化平缓还是剧烈,马铃薯贮藏室内北墙体附近温度均处于基本稳定状态;马铃薯种子的呼吸作用对贮藏室内温度存在一定程度的影响。马铃薯种子贮藏中期贮藏室内北墙体附近温度高于马铃薯种子的适宜贮藏温度,而贮藏后期贮藏室内北墙体附近温度低于马铃薯种子的适宜贮藏温度。通过Fluent软件对贮藏室内北墙体温度进行数值模拟并与试验结果对比,得出实测值和模拟值吻合度较高的结论。
The test and analysis of the temperature of the northern wall in semi-underground potato storage in cold and semi-arid areas were conducted. The results showed that the temperature near the north wall of the potato storage room was basically stable no matter the outside weather changed gently or violently. The respiration of potato seeds had a certain influence on the temperature inside the storage room. The temperature near the northern wall of potato seed storage medium was higher than the suitable storage temperature of potato seeds, while the temperature near the northern wall of potato storage was lower than the suitable storage temperature of potato seeds. Fluent software was used to simulate the temperature of the north wall in the storage room and the result was compared with the experimental results. The conclusion was reached that the measured values and the simulated values were in good agreement.
