Analysis of Energy Dissipation of Interval-Pooled Stepped Spillways. [PDF]
Entropy (Basel), 2022 The water flow characteristics over an interval-pooled stepped spillway are investigated by combining the renormalization group (RNG) k-ε turbulence model with the volume of fluid (VOF) interface capture technique in the present study.

Capturing Free Surface Dynamics of Flows over a Stepped Spillway Using a Depth Camera. [PDF]
Sensors (Basel)Spatio-temporal measurements of turbulent free surface flows remain challenging with in situ point methods. This study explores the application of an inexpensive depth-sensing RGB-D camera, the Intel® RealSense™ D455, to capture detailed water surface ...

Stepped spillway design for energy dissipation
Water Science and Technology: Water Supply, 2023 Important water structures known as stepped spillways are used to dissipate energy, aerate rivers, and reduce the cost of the downstream pool. The aim of this study is to increase the energy dissipation rate by proposing an alternative design to the ...

Effect Of Pooled and Flat Stepped Spillway on Energy Dissipation Using Computational Fluid Dynamics
Tikrit Journal of Engineering Sciences, 2022 The goal of this research was to determine the impact of a pooled and flat stepped spillway on energy losses. FLOW3D, which is a computational fluid dynamics (CFD) program, with mesh size of 0.015 mm was used for this purpose. First, the code was tested

Effect of slope on energy dissipation for flow over a stepped spillway
Water Science and Technology: Water Supply, 2022 In a stepped spillway, the spillway face is provided with a series of steps from near the crest to the toe. This type of spillway is attractive for water resource management because it dissipates energy that is within the flow.

Effect of Height and Geometry of Stepped Spillway on Inception Point Location
Applied Sciences (Switzerland), 2019 Air entrainment in a stepped spillway is very important to protect the spillway from cavitation damage. The inception point is the location where air starts entering the non-aerated flow zone. The inception point location depends on different parameters,
