摘　　要：对Φ2 400 mm填料塔中槽式液体分布器的初始布液状况进行了数值模拟及试验,采用VOF模型处理主槽液面波动问题。结果表明,进料管冲击水柱会引起一级槽液面回流,湍动集中在冲击区域周围,进料管数量和液流速度是影响主槽液面波动和流场的主要因素,模拟结果与试验结果一致。Slotted liquid distributor suitable for packed column is studied in terms of liquid initial distribution in packed column （Ф2 400 mm in diameter） by numerical simulation and test. VOF model was used to deal with liquid surface fluctuation in main slot. As the result, impinging flow induce the reflux and turbulence energy concentrate on the impinging zones, liquid flow velocity and the number of inlet points are the important factors which affect liquid fluctuation and velocity distribution. Simulation results could accord with experimental facts on the whole.
