摘要
本文用FLUENT软件对间冷式冷藏箱的流场与温度场进行数值模拟,分别模拟了冷藏箱开机15分钟强制对流和停机3分钟自然对流时箱体内流场与温度场的分布情况。计算结果与实验测试结果互相一致,得出模拟结果的真实可靠性。模拟结果为箱体内流场与温度场的均匀性分布提供了理论支持,为改进箱体风道结构以及送回风方式做出初步探索。
The computational fluid dynamics （CFD） software FLUENT was used to simulate the temperature field and flow field inside an indirect cooling freezer. It simulated the distribution of temperature field and flow field inside the cabinet with force convection in 15 minutes and the natural convection in 3 minutes. The computing results matched well with the experimental results, and the dependability of the simulation results was obtained. It provides theoretical support for uniform distribution of temperature field and flow field inside the cabinet, making a preliminary exploration to improve the box structure and air supply.
