指出了Beggs-Brill截面含液率计算模型在计算下倾管路时存在的问题,并从数学上进行了分析,推导得出了截面含液率计算公式在计算下倾管时的使用范围。提供了一种用于管路持液率计算的方法,可以用于水平管、上倾管和下倾管的计算,并利用实验数据对两者的计算结果作了比较。
The problems existing in the calculation of pouring line of Beggs-Brill cross-sectional liquid rate model were pointed out. The mathematical model was used to calculate the liquid content of Beggs-Brill model. A method for calculating the liquid holdup of a pipeline is provided, which can be used to calculate the horizontal pipe, the upper pipe and the downpipe, and the experimental results are used to compare the calculated results.
