The weeping phenomenon was investigated using some experimental tests and a numerical model. The tests were performed within a 1.22‐m‐diameter pilot‐scale column including two chimney trays and two Nye test trays with an air‐water system. The rates of weeping were measured in the Nye trays with two heights of the weir and a hole area of 5 %. Moreover, the weeping rates in the outlet and inlet halves of the Nye tray and the total weeping rate were calculated. In the next step, an Eulerian‐Eulerian computational fluid dynamics (CFD) technique was used. The results show good agreement between the attained CFD findings and the experimental data.

计算流体动力学与实验：对Nye托盘的液体渗漏的研究
使用一些实验测试和数值模型研究了哭泣现象。测试在直径1.22米的中试规模的色谱柱中进行，该色谱柱包括两个烟囱式塔盘和两个带空气系统的Nye测试塔盘。在具有两个堰高和5％的孔面积的Nye托盘中测量了渗出率。而且，计算了Nye塔盘的出口半部和入口半部的哭泣率和总哭泣率。下一步，使用了欧拉-欧拉计算流体动力学（CFD）技术。结果表明，获得的CFD结果与实验数据之间具有很好的一致性。
