Résumé

The study experimentally investigated the effect of flow directions and other flow parameters on two-phase distribution characteristics of R-22 at a T-junction. As geometric parameters, the direction of the inlet or branch tube was chosen. As inlet flow parameter, the inlet mass flux and quality were varied from 100 to 700 kg/m2.s and from 0.1 to 0.9, respectively. The measured data were compared with the values predicted by the models developed for air-water or steam-water mixture in the literature. The authors proposed a modified model for application to the reduced T-junction and vertical upward and downward directions of inlet and branch tubes. Among the geometric parameters, the branch tube direction showed the largest sensitivity to the mass flow rate ratio for the gas phase, while the inlet quality showed the largest sensitivity to the mass flow rate ratio among the inlet flow parameters.
