The hydrodynamic characteristics of downwards co-current two-phase (gas-liquid) flows inside a vertical tube (ID = 32 mm) have been investigated experimentally. Advanced optical techniques, namely Laser Induced Fluorescence and Particle Tracking Velocimetry, were utilised for the characterisation of these flows over a wide range of gas and liquid superficial velocities (U G = 0 -34 m·s -1 and U L = 0.034 -0.182 m·s -1 ), corresponding to Reynolds numbers Re G = 0 -84,600 and Re L = 1,230doi:10.1615/ichmt.2012.procsevintsympturbheattransfpal.820 fatcat:tz3my46dwbdqvjtvy6ivdd7k2q
