Gas-liquid plug flow liquid holdup measurement using semantic segmentation
You-qi chuyun, 2021 Liquid holdup is one of the most important parameters of gas-liquid two-phase flow. Affected by the image noise, the traditional liquid holdup measurement method based on image processing is difficult to accurately extract the gas-liquid interface ...
