Abstract: In the present paper, three-dimensional, unsteady, Detached Eddy Simulation (DES) of a submerged hydraulic jump with an inlet Froude number of 8. 2 is performed. Volume of Fluid (VOF) method is used for free surface tracking along with High Resolution Interface Capturing (HRIC) .The results of the simulation is compared with existing experimental data. The three dimensional nature of flow close to the sluice gate captured by the present simulation is clearly depicted. Turbulence parameters including Reynolds stresses are reported. Proper Orthogonal Decomposition (POD) analysis of the velocity field was carried out to identify the coherent structures. The details of this POD analysis are presented with relevant discussions.
