SPHysics Simulation of Experimental Spillway Hydraulics

SPHysics Simulation of Experimental Spillway Hydraulics

In this paper, we use the parallel open source code parallelSPHysics based on the weakly compressible Smoothed Particle Hydrodynamics (WCSPH) approach to study a spillway flow over stepped stairs. SPH is a robust mesh-free particle modelling technique and has great potential in treating the free surfaces in spillway hydraulics. A laboratory experiment is carried out for the different flow disch...

Photographic Techniques in Experimental Hydraulics

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Spillway Escapement of Muskellunge

Many of the quality recreational fishing opportunities in Illinois occur in reservoirs. Fish emigration from reservoirs during periods of overflow is termed “dam” or “spillway escapement.” Escapement can detract from recreational fishing opportunities in the reservoir and can disturb downstream ecosystems by creating an influx of unwanted and/or non-native fish. Previous research on spillway es...

Experimental Investigation of Dropshaft Hydraulics: Two-phase Flow and Acoustics

A dropshaft is an energy dissipator connecting two channels with different invert elevations. Detailed air-water flow and acoustic measurements were conducted in a prototype dropshaft under controlled flow conditions, and complemented by a 1:3.1 scale model study. Experimental observations showed three flow regimes with distinct acoustic signatures. Strong flow aeration was recorded in two flow...
