Chute roughness solutions for effective energy dissipation

The project aims to investigate and improve energy dissipation in spillway structures at hydropower dams, particularly in light of increased design flood flows. To meet these conditions, new types of bottom structures are being studied as a way to influence flow dynamics and thereby enable more controlled water discharge.

Laboratory models of spillways are constructed to analyze flow patterns, including flow depth, velocity, pressure, and the efficiency of energy dissipation. To complement the physical experiments, numerical simulations using CFD (Computational Fluid Dynamics) are employed to map turbulent flow structures and examine the mechanisms behind changes in energy dissipation.

The results from the project can be used to develop design recommendations that contribute to more efficient energy dissipation in spillway channels of existing dam facilities.
