The application of signal analysis techniques based on chaos theory to flow regime identification.

Rawes, W (1996-12)

The aim of the research presented in this thesis has been to develop an objective measurement technique to improve the detection of flow patterns in closed ducts. This activity is important for the safe and efficient running ...
Estimating slug liquid holdup in high viscosity oil-gas two-phase flow

Archibong-Eso, Archibong; Okeke, Nonso Evaristus; Baba, Yahaya D.; Aliyu, Abdulkabir; Lao, Liyun; Yeung, H. (Elsevier, 2018-10-29)

Slug flow is one of the most critical and often encountered flow patterns in the oil and gas industry. It is characterised by intermittency which results in large fluctuations in liquid holdup and pressure gradient. A ...
Interfacial friction in upward annular gas–liquid two-phase flow in pipes

Aliyu, A. M.; Baba, Yahaya D.; Lao, Liyun; Yeung, H.; Kim, K. C. (Elsevier, 2017-02-17)

Accurate prediction of interfacial friction between the gas and liquid in annular two-phase flow in pipes is essential for the proper modelling of pressure drop and heat transfer coefficient in pipeline systems. Many ...
Investigation and prediction of slug flow characteristics in highly viscous liquid and gas flows in horizontal pipes

Zhao, Y.; Lao, Liyun; Yeung, H. (Elsevier, 2015-06-18)

Slug flow characteristics in highly viscous liquid and gas flow are studied experimentally in a horizontal pipe with 0.074 m ID and 17 m length. Results of flow regime map, liquid holdup and pressure gradient are discussed ...
