The present investigation generated phase-distribution and pressure-drop data for air-water flows in a reduced horizontal tee junction. This junction consisted of a 38.1-mm I.D. inlet tube with a 7.85-mm I.D. branch tube, thus yielding a diameter ratio of {dollar}rm Dsb3/Dsb1=0.206.{dollar} The operating conditions were as follows: an inlet* pressure of 3.0 bar (abs), an inlet temperature near ambient, an inlet mass flux in the range {dollar}rm 11.5 le Gsb1le 181.5 kg/msp2s,{dollar} inlet superficial gas velocities in the range {dollar}rm 2.7le Jsb{lcub}G1{rcub}le 40.1 m/s,{dollar} superficial liquid velocities in the range {dollar}rm 0.0021le Jsb{lcub}L1{rcub}le 0.0398 m/s,{dollar} and extraction ratios in the range {dollar}rm 0.049le Wsb3/Wsb1le 0.904.{dollar} This combination of inlet conditions led to observed inlet flow regimes of stratified, stratified-wavy, wavy, semiannular, and annular.; The present data were compared against those of Walters (1994) under similar conditions with the exception of system (inlet) pressure. (Abstract shortened by UMI.) ftn*The word "inlet,"as used in this thesis, refers to the tee junction inlet. |
