论文笔记-Non-intrusive classification of gas-liquid flow regimes in an S-shaped pipeline riser using a Doppler ultrasonic sensor and deep neural networks 目标:使用深度神经网络对 S 形立管中的流态进行分类 该分类器与四种传统的机器学习分类器进行了比较:即 AdaBoost 分类器、bagging 分类器、额外树分类器...
Due to the increased influence of the surface tension force and the frictional shear stress in channels with a micro-gap, the liquid droplets adhered on the wall surface and were pushed by the gas phase. Flow regimes in these micro-gaps can be classified into cap–bubbly flow, slug–droplet...
Gas-liquid flows in annulus channels are frequently encountered in the underbalanced drilling operation when the gasified drilling fluid is used. Accurate characterization of two-phase flow regimes in such conduits is critically important in order to gain a better understanding of the flow behaviours ...
design and working parameters of bubble column reactors on the formation and stability of the homogeneous and the heterogeneous bubbling regimes and to demonstrate the effect of bubbling regime transition on the hydrodynamic and mass transfer characteristics of gas-liquid beds in bubble column reactors....
摘要 The knowledge of flow regimes is very important in the study of a two phase flow system. A new flow regime identifica... 关键词 flow regime identification / probability density function (PDF) / neur...
The drift flux model could best be applied to the reminder of the data when the plug and churn-turbulent flow regimes were treated together, and the slug flow was treated separately. The drift flux parameters depended on the pulp consistency. 展开 关键词: Pulp Fiber slurry Three-phase flow ...
Based on physical concepts, a theory is developed to predict the transition boundaries for various flow regimes for nonfoaming liquids. The effects of ... KM Ng - 《Aiche Journal》 被引量: 177发表: 1986年 Pressure Drop and Liquid Holdup in Trickle Flow Reactors: Improved Ergun Constants and...
Experimental study has been aimed at examining the flow regimes of gas-liquid in up-flow ejectors by planar laser induced fluorescence (PLIF). technology under air-water and carbon dioxide-water system, the velocity fields by particle image velocimetry (PIV). under carbon dioxide-water system and...
Gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, churn and annular. Considering each numerical method to be appropriate for modeling a certain flow regime, a suitable numerical approach ...
The formulation predicts the development of flow regimes and various flow parameters without the need for maps, or the need to change closure relationships. To accomplish this, the model includes four fields, i.e. continuous and dispersed liquid, continuous and dispersed gas, as well as a set ...
