Flow regime identification for upward two-phase flow in helically coiled tubes

Chemical Engineering Journal, 2017
Abstract Helically coiled tubes have excellent compactness, heat transfer efficiency, thermal stress adaptability and two-phase flow stability. The increasing application of two-phase flow in helically coiled tube devices necessitates a deep knowledge of phase distribution features for different flow regimes as well as flow regime transitions ...

Flow regime identification for air valves failure evaluation in water pipelines using pressure data [PDF]

Water Research, 2019
Air valve failure can cause air accumulation and result in a loss of carrying capacity, pipe vibration and even in some situations a catastrophic failure of water transmission pipelines. Air is most likely to accumulate in downward sloping pipes, leading

Flow Regime Identification in Large Diameter Pipe

Volume 3: Thermal Hydraulics; Instrumentation and Controls, 2008
Air-water vertical two-phase flow experiments were performed in a 0.15 m diameter and 4.4 m long test section. Superficial liquid velocity was varied from 0.05 m/s to 2.0 m/s and superficial gas velocity was varied to obtain the area averaged void fraction range of 0.1 to 0.7. Exit pressure was close to the atmospheric pressure.

Identification of fluid flow regimes in narrow cracks

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2000
The problem of fluid seepage through the cracked walls of pressure vessels has been examined. A simplified two-dimensional computational fluid dynamics (CFD) model of water passing through a narrow crack has been constructed and the results compared with published data.

Neural Networks for Flow Regime Identification with dry particulate flow

Particle & Particle Systems Characterization, 1993
AbstractThis work on imaging of particulate processes using electrical charge tomography uses two basic techniques: the multi‐sensing of electrical charge in a cross‐section of the flow pipe and a neural network based flow regime identification system to aid in the image reconstruction process.A measurement system, consisting of sixteen sensors, placed

Flow regime identification using chaotic characteristics of two-phase flow

Nuclear Engineering and Design, 2008
Chaotic nature of two-phase flow is investigated for its dependency upon the flow regime by constructing the pseudo phase space with the time sequential impedance signals of the void fraction. In order to construct the pseudo phase space, the autocorrelation function (ACF) and the average mutual information (AMI) for the delayed time, and the false ...

Flow regime identification for wet gas flow based on WPT and RBFN

2009 IEEE International Conference on Intelligent Computing and Intelligent Systems, 2009
A novel noninvasive approach to the on-line flow regime identification for wet gas flow in a horizontally mounted pipeline is proposed in this paper. Research into the flow-induced vibration response for the wet gas flow with the conditions of pipe diameter 50mm, pressure from 0.25MPa to 0.35MPa, Lockhart-Martinelli parameter from 0.02 to 0.6, and gas ...

Flow Regime Identification in Boiling Two-Phase Flow in a Vertical Annulus

Journal of Fluids Engineering, 2011
This work describes the application of an artificial neural network to process the signals measured by local conductivity probes and classify them into their corresponding global flow regimes. Experiments were performed in boiling upward two-phase flow in a vertical annulus.
