Characterizing gas-liquid two-phase flow behavior using complex network and deep learning.
Chaos, 2023Gas-liquid two-phase flow is polymorphic and unstable, and characterizing its flow behavior is a major challenge in the study of multiphase flow. We first conduct dynamic experiments on gas-liquid two-phase flow in a vertical tube and obtain multi ...

Acoustic emission-based flow noise detection and mechanism analysis for gas-liquid two-phase flow
Measurement, 2021The interphase forces of gas-liquid two-phase flow produce flow noise, which contains abundant two-phase flow information, such as two-phase flow rate, flow pattern, void fraction, etc.

Numerical investigation of gas-liquid two-phase flow in horizontal pipe with orifice plate
Progress in nuclear energy (New series), 2021Gas-liquid two-phase flow in horizontal or vertical pipeline significantly impacts on the transportation process. In fact, in the pipeline for regulating the flow flux or pressure, orifice plate and other current limiting device are frequently ...
