Complex Network and Bidimensional Multiscale Permutation Entropy: A New Method for Characterizing Nonlinear Dynamic Behavior in Gas-Liquid Two-Phase Flow

Revealing the evolutionary mechanisms of gas-liquid two-phase flow patterns is vital for production and transport in industry. The resistance sensor array is used to collect gas-liquid two-phase flow information from the vertical upward pipeline. The data are encoded into 2-D images using a Gramian...
