CFD Advocates a Hands Off Approach
In this case study, Computational fluid dynamics (CFD) software helps a UK consulting firm determine that, in this instance, the best course of action is to take no action at all.
Spillway Success
Making tailings safe: Tunisia-based engineering consultancy MECATER Ingénierie turns to FLOW-3D HYDRO to solve a critical environmental concern in New Caledonia.
Making The Mactaquac Dam New Again
A great deal of work remains before the Mactaquac Generating Station is restored. FLOW-3D HYDRO has allowed Hatch to identify the best approach moving forward, giving them a solid footing to plan and design future improvements and refurbishment. It allowed them to pinpoint the most effective way to improve hydraulic performance and reduce the risk of future erosion in the most efficient and cost-effective possible way.
Reconstruction and Extension of the Méricourt Locks: Study of Hydraulic Operations
The BRL ingénierie teams modeled the Mericourt locks using transient 3D CFD hydraulic analysis with FLOW-3D HYDRO.
EREDOS PROJECT: Numerical Modeling of Flows in Covered Streams
As part of the EREDOS project, BRL ingenierie used FLOW-3D CFD software to numerically model the issues associated with covered streams.
Siphon Spillways
Northwest Hydraulics Consultants has applied CFD modeling in numerous case studies of existing or new spillway designs. The following article demonstrates a sample case study conducted on an existing siphon spillway.
Hydraulic Jump in a Trench Type Pump Sump
Hydraulic jumps are a flow phenomenon familiar to people working with open channel applications. Wikipedia defines a hydraulic jump as “a condition where open channel flow abruptly transforms from super- to sub-critical.”
Mitigating Total Dissolved Gas at Boundary Dam
The Boundary Dam is located on the Pend Oreille River in northeastern Washington. The project consists of a 340 ft. high concrete arch dam, seven low level sluiceway outlets, two high level overflow spillways (Spillway 1 and Spillway 2), and an approximately 1,003 MW authorized capacity powerhouse.
Spillway Hydraulics Assessments
BC Hydro, a public electric utility in British Columbia, uses FLOW-3D to investigate complex hydraulics issues at several existing dams and to assist in the design and optimization of proposed facilities.
Turbulent Dispersion Modeling of Environmental Discharges
Environmental discharges and outfall structures have been traditionally designed by means of complex, cost-intensive and time-consuming experimental studies.
Fish Ladder Design
In this study, FLOW-3D played in instrumental role in the design of an innovative fish baffle for use within fish ladders used to regain lost riverine fish habitats
Indianapolis Storm-Water System
Sewer systems don’t seem very exciting unless they serve as action-movie get-away routes. Most likely you don’t even think about them until torrential rain brings water up to curb-level.
Validation of a 3D Dam Breaking Problem
A 3D dam breaking with obstacle configuration was chosen as one of our validation cases in order to assess FLOW-3D’s performance for the simulation of free-surface flows.
Grit Chamber Modeling
A continuous input of suspended sediment at the chamber inlet tunnel is being investigated with the help of FLOW-3D for different pumping rates.
Hydrodynamic Screws
The use of small-scale hydro power is becoming more interesting as a way to control the increasing costs of energy.
