Based on analysis of flow mechanism, a hydrodynamic model of slug flow in vertical pipes was developed considering the variable thickness of liquid film.
基于流动机理的分析建立了塞状流参数预测模型；模型中考虑了液膜的厚度变化。
2
The radial load has quite influences on the film thickness and hydrodynamic pressure.
渗透度对压力分布、油膜厚度也有一定影响。
3
The model is solved by using multi-grid method. Then obtain the hydrodynamic pressure and oil-film thickness distribution.
