This study presents a three dimensional CFD model of the air-water flow in a free surface discharge tunnel of a typical bottom outlet with a high head gate. The numerical simulation is performed in ANSYS-FLUENT. Results of volume fraction, velocity, and pressure fields are analyzed for two gate openings, i.e. 54% and 100%. The free surface flow in the conduit is calculated by means of the VOF method. Finally, a novel methodology is presented to calculate the air demand distribution as part of the design of the aeration system in bottom outlets with high head gate
