基于CFD的沙漠环境模拟实验室改进设计研究

Improved Design of the Desert Environment Simulation Laboratory Based on CFD

采用制冷空调技术和通风、变频技术相结合的方法对沙漠环境模拟实验室进行了温度环境模拟与阵风环境模拟的改进设计;应用CFD方法对改进后实验室的三维温度场和速度场进行了模拟,模拟结果显示,实验室模型实验区温度场和速度场的均匀性有了显著的提高,涡旋的影响显著减弱,达到了模拟指标的要求。

The simulation on temperature and gust of Desert Environment Simulation Laboratory was improved by combining the technologies of refrigeration and air-conditioning with ventilation and frequency conversion. The temperature field and velocity field of the improved laboratory were simulated through CFD technique. The results show that uniformity of the two fields is dramatically improved and the scroll influence is greatly reduced, which meet the requirements of simulation indexes.
