[en] Two- and three-dimensional numerical models TELEMAC-2D and TELEMAC-3D are used for simulating laboratory experiments of steady flow in shallow rectangular reservoirs. Using TELEMAC-2D, various user-defined parameters and options are tested. In particular, six turbulence models are evaluated, along with a mesh grid size sensitivity. Using the finite element and finite volume approaches, several numerical schemes for solving the advection step for velocity and turbulence are compared. For all laboratory configurations, the measured and computed horizontal velocity fields are compared. Satisfactory results are obtained with TELEMAC-2D using the Spalart-Allmaras turbulence model. The effect of numerical scheme is very weak. A comparison between TELEMAC-2D and TELEMAC-3D is performed using the k–ε turbulence model with LIPS scheme for the particular C-C reservoir configuration. The 3D simulations slightly improve the results.
