AB  - An experimental and numerical study is carried out of two-phase flow phenomena in a divergence ribs rectangular duct for two positions: vertical and inclined (65° with horizontal) with two opening divergence angles. The experiments are performed in the duct with the water-air flow with various water and air discharges. The purpose of the these study to visualize the two phase flow phenomena in addition to studying the effect of the pressure difference through the divergence. All the experimental data in this study are achieved by utilizing a pressure sensor and imagined by a video camera for various water discharges (5, 15 and 20 L/min), various air discharges (8.333, 10.833 and 16,666 L/min) and the opening angles are 10 and 15°. The results show that when the opening divergence angle increases from (10-15) at constant air and water discharge, the pressure recovery through the divergence ribs rectangular duct section decreases by 11%.
