The results show that the particle size has a core-annular flow pattern in radial position and solid volume fraction is much denser at the bottom of the riser.
结果表明：颗粒在管内呈环—核流动结构，固含率在轴向上呈“上稀下浓”的分布特征。
Its basic principle is that there is a quite steady flow state of annular flow in the flow pattern of gas-liquid two-phase flow.
模型是建立在压力能量消耗率最小的原理上的，其基本原理是：在气-液两相流的流型中，环状流具有相当稳定的流动状态。
The accuracy of flow pattern identification of stratified flow, annular flow, core flow and homogeneous flow is more than 95% and the speed of flow pattern identification is less than 0.3s.
对于层状流、核心流、环状流、均相流等流型，流型辨识的准确率高于95%，辨识一个流型所用的时间小于0.3秒。
