Abstract Important water structures known as stepped spillways are used to dissipate energy, aerate rivers, and reduce the cost of downstream pool. The aim this study is increase energy dissipation rate by proposing an alternative design flat spillways, which frequently in practice. For that reason, Circular Stepped Spillway (CSS) has been constructed numerically investigated paper. CSS spillwa...

This study offers a novel empirical equation for those involved in ski-jump type energy dissipator, stilling basin, and plunge pool designs to determine the dissipation level due air resistance. The verified by conducting experimental, empirical, numerical regression analyses at prototype scale. Energy resistance can then be easily calculated discharges reaching up 10000 m3/s using equation.

Energy dissipation on collisions of grain aggregates is investigated taking into account effects by sintering. It is shown that sintering significantly reduces the energy dissipation efficiency because contacts between adjacent grains become strong by sintering.

Integrating wave energy converters with breakwaters is a promising concept for wave energy utilization. On the basis of fulfilling the wave protection demands, pile-supported Oscillating Water Column (OWC)-type breakwaters can also meet the local needs of electricity far from the lands. In the present study, the wave energy extraction and vortex-induced energy loss of pile-supported OWC-type br...

The efficiency and product quality of hydro-abrasive machining (HAM) could be considerably improved if the energy dissipation phenomenon of the jet-like tool during the material removal is clearly understood. An on-line technique for quantifying the amount of energy dissipated in the workpiece during HAM using acoustic emission (AE) measurements is presented in this paper. The measured AE-signa...

Mechanical stimulation has been proposed to induce chondrogenesis in cell-seeded scaffolds. However, the effects of mechanical stimuli on engineered cartilage may vary substantially between different scaffolds. This advocates for the need to identify an overarching mechanobiological variable. We hypothesize that energy dissipation of scaffolds subjected to dynamic loading may be used as a mecha...
