Educational Application of Flow3D Software for Turbulent Modeling in 3D Simulation of Hydraulic Jump in Stilling Basin with Concrete Baffles

In this paper, hydraulic jump which is one of the effective means of energy dissipation of supercritical flow in hydraulic engineering is simulated using Flow 3D software. This software utilizes VOF method for tracing the free surface position and FAVOR method for considering the baffles inside the computational domain. First, the accuracy of the software application in forecasting hydraulic jump flow parameters is assessed by comparison of computed parameters using k-ε andRNG turbulent modeling strategies with readily available experimental measurements.  Then, the software is utilized for simulation of hydraulic jump in a small scale laboratory stilling basin with baffles. The computed velocity profiles and water surface level present good agreements with the reported laboratory measurements.
