本研究通过实验和数值模拟研究了3D对开放式冷藏陈列柜（ORDC）性能的影响。采用考虑浮力效应的k-e-e湍流模型进行了三维仿真，并与二维仿真模型的结果进行了比较。结果表明，三维模拟的入渗速率明显大于二维模拟，表明三维流场的重要性，在ORDC的CFD分析中不应忽视。模拟还表明，湍流强度对ORDC的性能有很大影响。当湍流强度从25%降低到5%时，第一层和第六层之间的温差可以从11°C降低到5°C（19.8°F到9°F），渗透率可以降低25%。根据货架内部的温度分布进行了三维计算，并与测量结果进行了比较，结果表明两者吻合良好。 单位:双引文:ASHRAE交易，第115卷，第。2、路易斯维尔2009

This study experimentally and numerically examines the 3D effect on the performance of an open refrigerated display cases (ORDC). Three dimensional simulation model with k-e-E turbulence model incorpating the buoyancy effect is carried out to compare with the results by 2D simulation model. It is found that the infiltration rate of 3D simulation is significantly larger than that of 2D simulation, indicating the importance of 3D flow field, and it should not be neglected in CFD analysis of an ORDC. The simulation also suggests that turbulence intensity cast a considerable influence on the performance of ORDC. When the turbulence intensity is reduced from 25% to 5%, the temperature difference between the first and the sixth shelf can be reduced from 11°C to 5°C (19.8°F to 9°F) and the infiltration rate can be reduced by 25 percent. The 3D computations in terms of temperature distribution inside the shelves were compared with the measurements, and good agreement are reported.Units: Dual
