Simulation of two-phase air / water flows in bubbly flow in horizontal pipe

Résumé

This study presents the two-phase CFD simulation of horizontal pipe flow experiments carried out on METERO-H facility in the frame of a Loss-Of-Coolant Accident (LOCA). The computational domain is based on conformal hexahedral mesh. A mesh sensitivity study was performed with a comparison with experimental data. A sensitivity study on number of field used in the modelling was performed. The three fields approach permits to well reproduce the experiments at high void fraction while the two fields approach underestimate the void fraction within the upper part of pipe. Results are in good agreement with experimental data.
