Modelling near-bank flow hydraulics
River bank erosion models are a fundamental requirement for understanding the migration and evolution of river meanders, estimating the potential for land-loss and threat to floodplain infrastructure, and predicting the delivery of contaminated floodplain sediments to aquatic ecosystems. While …

Coupling of system thermal-hydraulics and Monte-Carlo method for a consistent thermal-hydraulics-reactor physics feedback
… reactor physics code, Serpent, with thermal-hydraulics safety analysis code RELAP5-3D. Thermal-hydraulics and reactor physics coupling is commonly used in deterministic methods, for example RELAP5/PARCS and TRACE/PARCS. It has been well-validated for a number of steady and transient problems. …

Culvert Hydraulics: Comparison of Current Computer Models
… are available to assist in analyzing culvert hydraulics, some of which include HY-8, Fish X-ing, Broken-back Culvert Analysis Program (BCAP), Hydraflow Express, Culvert Master, Culvert, and Hydrologic Engineering Center River Analysis System (HEC-RAS). While all of these programs can simulate …

Numerically Simulated Soil Surface Degradation (Erosion, Hydraulics)
Accelerated soil erosion is a serious problem because it destroys the land were it occurs and the resulting sediment pollutes the waters where it is carried and deposited. Experimental studies have led to the development of empirical equations describing soil erosion. Mathematical representations …

Adaptive Hydraulics for Improved Centrifugal Pump Efficiency
Centrifugal pumps are used ubiquitously for fluid transport in industrial and municipal systems including: clean and waste water systems, pumped hydro energy storage, closed loop HVAC heating, and irrigation. Globally, pumps consume hundreds of billions of kilowatt hours of electricity each year. …

Hydraulics and instabilities of quasi-geostrophic zonal flows
… have examined specific examples of shear flow "hydraulics", my goal was to find general criteria for the types of flows that may exhibit hydraulic behavior. In addition, a goal was to determine whether a hydraulic mechanism could be important if smaller scale shear instabilities were present. A …

A critical review of measurement techniques in coastal hydraulics
… measurement techniques in the field of coastal hydraulics. Techniques of wave measurement are studied in detail 1 and the analysis of wave measurements is then dealt with. Particular attention is paid to the analysis of one-dimensional wave energy spectra. Two computer programs were adapted for …

Outcomes of river rehabilitation on instream hydraulics and fish communities
… composition and structure.Variation of instream hydraulics was assessed before and after the rehabilitation to investigate the environmental outcomes of river rehabilitation schemes. Little significant change in hydraulic conditions was observed following river rehabilitation at all sites …

Downstream change in channel hydraulics along the River Severn, UK
An understanding of the longstream distribution of hydraulic processes is important for evaluating the mechanisms which control the catchment-scale variation of channel stability, sediment transport and siltation, flood generation and aquatic habitats. However, little attention has been given to …

Tightly coupled neutronics and thermal-hydraulics using open-source software
… using two 1.5-D (1-D neutronics and 2-D thermal-hydraulics) examples: a symmetric unit cell and an asymmetric unit cell. The mesh of the tightly integrated computation is 25 % and 12 % coarser than the loosely coupled one for the symmetric case and the asymmetric case, respectively. Starting from …

Scale adaptive turbulence modeling for in-vessel sodium thermal hydraulics
Computational fluid dynamics is a powerful tool for the simulation of nuclear reactor coolant flows, such as in sodium fast reactors. In these reactors, the phenomenon of thermal striping -- characterized by oscillatory turbulent mixing of non-isothermal coolant flows -- has the potential to damage …
