为了研究货物堆码方式对冷藏集装箱内温度分布的影响,以20英尺冷藏集装箱为研究对象,建立箱内空气对流与换热的物理和数学模型。采用标准k-ε紊流计算模型,对稳态下的箱内温度分布情况进行模拟仿真。在装载货物量不变的情况下,通过改变冷藏货物的配载方式,采用CFD软件模拟了箱内温度场分布。结果表明:货物左右对称装载方式的温度场分布情况优于货物整体装载方式;合理的控制货物转载高度、货物与箱壁侧面间隙可以有效防止湍流现象的发生。
In order to study the influence of stacking method on the temperature distribution in refrigerated containers, a 20-foot refrigerated container was chosen as the research object to establish the physical and mathematical models of air convection and heat exchange in the container. The standard k-ε turbulence model was used to simulate the temperature distribution inside the box under steady-state conditions. In the case of the same load of goods, by changing the way of loading the refrigerated goods, the CFD software was used to simulate the temperature distribution inside the box. The results show that the distribution of the temperature field of the bilateral symmetrical loading is better than that of the whole loading. Reasonable control of the reloading height and the clearance between the cargo and the side wall can effectively prevent the occurrence of turbulence.
