Two-phase flow pressure drops at the junction were measured in the Freon loop. The loop has two channels, the main and branch, which combine horizontally at the angle of 90 or 45 degrees. Each pressure drop of the junction is obtained by subtracting the frictional and accelerative pressure drop from the measured pressure difference. The junction pressure drop coefficient, defined as the pressure drop divided by the momentum flux after combination versus the ratio of the momentum flux of the branch to that of the main channel after combining, explained the characteristics of the junction pressure drop well. The junction pressure drop coefficients of 45 degree were less than those of 90 degree, and the values at the branch channel became similar to those of 90 degree when the momentum flux was large.
