The forecast of the operating conditions of a spillway or a dam is one of the industrial sectors where the tools used by XC Engineering give their best.
The bibliography in this field is large, and XC Engineering daily works with high-level industrial entities providing its CFD experience on these topics.
One of the strength points of the tool used by the society (FLOW-3D) is the accuracy in free-surface shape reproduction and the possibility to enrich the calculation with moving elements, like gates, simulating the opening or closing transients.
The numerical simulation with FLOW-3D aloud to preview the discharge coefficient of a spillway, as well as other typical interesting quantities as the hydraulic energy, dissipation, air entrainment. It is possible to analyse standard spillway shapes or innovative and complex ones, like those designed inside major European Research Centres.
The modelling can be done in 2D (for very fast analysis) or in 3D, for a more accurate study on the environmental impact of the structure in its real operating condition.
The CFD application on dam design covers almost every single actor involved in it. It is possible to simulate the efficiency of a water intake in its specific working topography, evaluating the generated external field, stagnation or recirculation zones, verify the environmental impact. Similar outputs for outflow ducts or internal details.
