摘　　要：通过对小孔筛板的流体力学实验研究给出了筛板上清液层高度的测量结果,实验在塔径为1.2 m的冷模精馏塔中应用空气-水系统进行。利用实验数据对文献中用于计算筛板上清液层高度关联式中的拟合参数进行重新回归,通过比较得出能够更好地预测小孔筛板上清液层高度的关联式。The experimental study on fluid hydraulics of small-perforated sieve tray with an air-water system in a 1.2 meters diameter column is made,and it can give a result of clear liquid height.The coefficients in the correlations,which are used for calculating clear liquid height of sieve tray,cited in literature,are correlated again by analyzing experimental data.A better one for predicting clear liquid height on small-perforated sieve tray is found by comparing them.
