Countercurrent gas-liquid flow in a hot leg under reflux cooling - numerical calculations for air-water tests at FZD

Murase, M.; Kinoshita, I.; Utanohara, Y.; Lucas, D.; Vallée, C.; Tomiyama, A.

Numerical calculations using FLUENT6.3.26 were conducted for air-water CCFL tests using the 1/3rd scale rectangular channel simulating a PWR hot leg at FZD, and the results were compared with CCFL characteristics in circular tubes.

Keywords: PWR; reflux cooling; hot leg; countercurrent gas-liquid flow; numerical calculations
