NON-INVASIVE ON-LINE TWO-PHASE FLOW REGIME IDENTIFICATION

Computational Intelligence in Decision and Control, 2008
A novel non-invasive methodology is proposed for the classification of BWR two-phase flow regimes. Neutron radiography images (frames) of coolant flow recordings (videos) are used. Following image pre-processing via directly computable statistical operators, the extracted statistical characteristics are input into an ensemble of self-organizing maps ...

Identification of Two-Phase Flow Regimes by an Optimum Modeling Method

Nuclear Technology, 1988
A new technique of identifying the flow regimes of air/water two-phase flow in a vertical pipe is proposed. This technique is based on analyzing the statistical characteristics of the static and differential pressure signals by an optimum modeling method.

Intelligent Identification of Flow Regime Based on a Novel Neural Network

Applied Mechanics and Materials, 2014
A noveol neural network of Elman is typically dynamic recurrent neural network. A novel method of flow regime identification based on Elman neural network and wavelet packet decomposition is proposed in this paper. Above all, the collected pressure-difference fluctuation signals are decomposed by the four-layer wavelet packet, and the decomposed ...

Intelligent Identification of Flow Regime Based on Improved BP and IMFs

Advanced Materials Research, 2013
Aimed at the characteristic of nonlinear and non-stationary of pressure drop, in this article a flow regime identification soft sensing method using Hilbert-Huang transformation combined with improved BP neural network is put forward. The method analyzes the intrinsic mode function (IMFs) obtained after the empirical mode decomposition (EMD), then ...
