上流部に曲がり管を備える垂直Y字管におけるR32の分流特性

Two phase flow distribution for split flow in Y junction after horizontal to vertical 90° elbow tube are evaluated through experimental and analytical approaches. In the experiment, the dependency of distribution on structural parameters such as orientation angle of elbow tube as well as operating conditions such as inlet flow rate and quality. The distribution in Y junction was found to depend strongly on both orientation angle and split ratio as evaluated in both experimental and prediction model.
