Abstract

Hydraulic jump is one of the most extended and effective mechanism for hydraulic energydissipation. Usually, hydraulic jump characteristics have been studied through physical models.Nowadays, computational fluid dynamics (CFD) are an important tool that can help to analyzeand to understand complex phenomena that involve high turbulence and air entrainment cases.Free and submerged hydraulic jumps are studied in a rectangular channel downstream a sluicegate. Velocity measurements are carried out by using an Acoustic Doppler Velocimeter (ADV)and a Particle Image Velocimeter (PIV). The CFD models boundary conditions are based onlaboratory measurements. Air-water two-phase flows are considered in the simulations. Theclosure problem is solved by using a two-equations turbulence model. Water dep
