Two-phase flow characteristics across sudden contraction in small rectangular channels

This study examines the two-phase flow pattern change and pressure drop at the sudden contraction from small rectangular channels (3 × 9 mm and 3 × 6 mm) into a 3 mm diameter tube. A unique deflection of contraction pressure drop vs. vapor quality is observed at a very low quality regime with an unu...
