Vertical upward flow patterns in small diameter tubes

, 2005
Two-phase flow patterns were studied in vertical small diameter tubes using R134a as the working fluid. The observed flow patterns include bubbly, dispersed bubble, confined bubble, slug, churn, annular and mist flow.

Bubble-Forming Regime Identification Based on Image Textural Features and the MCWA Feature Selection Method

IEEE Access, 2017
Knowledge of the bubble-forming regime is important for studying the mechanism of gas-liquid two-phase flow. The process of bubble formation through an underwater nozzle at the bottom of a rectangular tank was observed using a high-speed camera.
