New neural network estimates gas-liquid flow void fraction from video

Researchers have developed VFNet, a novel dual-branch spatio-temporal neural network designed to estimate void fraction in gas-liquid two-phase flow using synchronized multi-view videos. This model addresses limitations of existing methods, which either rely on non-generalizable flow assumptions or intrusive sensing techniques. VFNet's architecture includes a local branch for feature extraction from confined regions and a spatio-temporal branch for capturing global flow evolution. Trained on computational fluid dynamics (CFD) data, VFNet demonstrates superior performance across various metrics and enhances downstream flow-pattern classification. AI
