Calderon, David. (2018). CFD Simulation Of The Air-Water Flow In The Bottom Outlet Of Ituango Hydroelectric Project. Daniel Bung, Blake Tullis, 7th IAHR International Symposium on Hydraulic Structures, Aachen, Germany, 15-18 May. doi: 10.15142/T3TW7D (978-0-692-13277-7).
Abstract
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 gates
