ONE-DIMENSIONAL MIXTURE MODEL CODE FOR THE MODELING OF TWO-PHASE FLOW THERMOSIPHON

Résumé

The numerous coupled physical phenomena involved in natural circulation two-phase flow loops make their analytical or numerical modelization difficult. A 1D mixture model code has been developed for the sizing of semi-closed thermosiphon loops. The results of the code have been compared to existing experimental data of several two-phase flow thermosiphons. A reasonable agreement was found between the experimental and computed mass fluxes. Additionally, a sensitivity analysis was conducted on the pipe diameter, the imposed pressure, and the position of the condenser. The model was finally used to size an experimental thermosiphon loop.
