Abstract: This article presents the results of experimental and numerical investigations of hydrodynamic forces acting on the inferior beam of a radial gate considering different submergence levels. The physical model study was developed in a flat bottom flume, in which a segment gate, built on a 1:25 geometric scale, was installed. Tests were performed following the Froude similarity criterion and load cells were used to measure forces acting on the inferior beam of the gate. Numerical simulations were performed with OpenFOAM free software, using solver interFoam and DES hybrid turbulence model (Detached-Eddy Simulation). The numerical model was developed considering a three-dimensional section (slice) of the channel and the gate. The analyzes were carried out with the objective of validating the use of the computational model to determine the forces acting on the inferior beam of the gate, by comparing the measurements on the numerical model with the ones recorded on physical model.
