β¦ Synopsis
An mveswatron has been made of au-water Wow in Y-Junctions, which are frequently used m mdustnal appbcatrons The an-water flow IS stratdied m the sloping hmbs approachmg the Junction and this paper examines the phenomena occurring at the Junction and m the followmg freely dischargmg vertical pipe It IS shown that three flow regunes can exist m the vertical limb followmg the Junction freely-falling water, homogeneous flow of water and au, and flow of water Hrlth a smal1 amount of residual au accompanied by the flooding of the Junctton The flow regmes are described and predIctions for transitions between them are developed 2R -Lll c W8ter OUI Air out d-------I_ to"k _ Fe 1 Schematic dmgram of the experimental apparatus CESVol 33 No 3-E

## Abstract Experimental data on flow pattern transitions, pressure drop, and flow characteristics for cocurrent gasβliquid flow through packed columns in microgravity is analyzed. The pulse flow regime exists over a wider range of gas and liquid flow rates under microgravity conditions. Furthermor

Measurements have been made of the entrainment of water droplets in an air-stream when air and water flow concurrently up a vertical glass tube of O&n. diameter. It was found that the mass flow of entrained liquid varied with the air rate to the power 2% and the liquid rate to the power 1.5 when ann
