This article mainly introduces the prediction method of the flow pattern, pressure gradient and liquid holdup of two phase flow in horizontal pipelines.
本文着重介绍水平管中这种两相流动的流动型态、压力梯度和持液率的预测方法。
The theoretical analyses of the hydrodynamics under a strong interaction flow regime were conducted and data of the bed averaged dynamic liquid holdup were obtained.
对气液强相互作用下滴流床反应器内的流体动力学进行了分析讨论。
In spray region, the effective pressure drop is mainly dependent on the static pressure drop due to liquid holdup on the tray, its value is not affected by hole gas velocity.
The liquid holdup on a tray under spray conditions was measured. A formula to calculate liquid holdup was developed by the analyses of the experimental data.
Technological calculation in a hilly multiphase pipe flow includes flow pattern prediction , liquid holdup and pressure drop calculation and temperature prediction.
