Spillways are one of the most important parts of dams. There are several types of spillways, but they all play the same role. The flow through these structures is quite complicated hydraulically. The main focus of this study is the free surface flow in st... see more

Stepped spillway is a good hydraulic structure for energy dissipation because of the large value of the surface roughness. The performance of the stepped spillway is enhanced with the presence of air that can prevent or reduce the cavitation damage. The f... see more

Today several dams are equipped by the stepped spillways because of efficient for energy dissipation and of high contribution to the stability of these structures. The air-water flow on stepped spillway can prevent or reduce the cavitation damage. The air... see more

Stepped spillway is hydraulic structure designed to dissipate considerable kinetic energy because it's characterised by the large value of the surface roughness. On stepped chutes with skimming flow regime, the flow is highly aerated which can reduce the ... see more

The paper presents a numerical simulation of the transonic flow of steam with a non-equilibrium phase change. The flow of steam is approximated by a mixture model complemented by transport equations for moments. Proper formulation of the problem consists ... see more

As with most high-velocity free-surface flows, stepped spillway flows become self-aerated when the drop height exceeds a critical value. Due to the step-induced macro-roughness, the flow field becomes more turbulent than on a similar smooth-invert chute. ... see more

Small-scale hydropower is a robust and reliable form of sustainable energy supply in remote areas. On the one hand, the potential for hydropower generation depends on the specific climate in a given place, and precipitation above all. On the other hand, s... see more
