Aeration of a Submerged Jet-Flow Gate
Submerged operation of a jet-flow gate requires special treatment of the area downstream from the gate to avoid cavitation damage. The Bureau of Reclamation studied operation of a submerged...
Flow Transitions Around a Single Large Bed Element
A qualitative description of the characteristics of supercritical-to-subcritical flow transitions due to the presence of a single large bed element (LBE) in a laboratory flume is presented....
Numerical Accuracies in Steady Open Channel Flow
The authors have reviewed the accuracy of the individual terms and formulations of the conservation of energy equation as used within the constraints of steady open channel flow modelling....
Momentum and Kinetic Energy Coefficient Research?Ramp Flumes
In October 1984. Reclamation Hydraulic Branch staff members investigated the operation of the A-Canal ramp at Klamath Falls, Oregon. The ramp flume was completed in 1983 as a water measurement...
Critical Flow Through Bridge Piers
A physical model study was performed at California State University, Long Beach to investigate the location of critical depth within bridge piers in supercritical lined channels. This...
Three-Dimensional Modelling of Recirculation Behind a Groyne
Extensive investigation on the three-dimensional flow patterns behind a groyne have been carried out in a small-scale experiment. A three-dimensional hydrodynamic numerical model is verified...
Instability of Water-Fluid Mud Interface
Erosion and entrainment of fluid mud are treated by means of shear flow analysis. The water-fluid mud system is considered as a layered system of two continua separated by a distinct interface...
Slurry Removal From a 2-D Fluidized Region
A two-dimensional fluidization experiment is performed on fine sand with a 5.08 cm diameter source pipe with horizontally opposed orifices, 0.317 cm in diameter, spaced 5.08 cm. Slurry...
A Study on Estimation of Aquifer Parameters in Unsteady Seepage Flow
A method which automatically identifies aquifer parameters is proposed in this paper. The aim of this investigations is to estimate transmissivities and storage coefficients of unsteady...
3-D Cavity Flow Analysis by a New Fractional Step Method Based on the Finite Element Method
This paper describes a new finite element scheme for solving the time-dependent incompressible viscous fluid flow expressed in terms of the Navier-Stokes equations. The main feature of...
Limitation to Standard Parshall Flume Calibrations
Parshall flumes are widely used for metering open channel flows. An inspection of the original study which developed the rating equations indicates that the flumes were not tested for...
Selection of Hole Size for Fluidization Pipes
Two-dimensional fluidization experiments are performed on fine and medium coarse quartz sands at depths of 25.4 and 42 cm. Four supply pipes are used with orifice diameters of 1.587 mm...
A Semi-Empirical Model for an OC-OTEC Spout Flash Evaporator
A phenomenological model for the thermal-hydraulics of a spout flash evaporator is presented in this paper. The model considers the two-phase flow behavior both in the spout and in the...
Resin Transfer Process Modelling: Computational & Experimental
In most cases, the resin transfer molding (RTM) researcher has a fundamental understanding of composites and possibly some mold design experience. The areas of resin flow dynamics and...
Durability of High-Strength Concrete Containing Fly-Ash and Silica Fume
The durability of high-strength concrete made with local materials were tested with regard to the freezing and thawing resistance of concrete in accordance with ASTM C666 procedure A....
Stratified Flows
This volume contains the edited and refereed proceedings of the Third International Symposium on Stratified Flows, convened on February 3-5, 1987 in Pasadena, California. It consists of...
Probabilistic Prediction of Losses to Lifeline Systems Due to Earthquakes
An efficient and practical method for earthquake loss estimation for lifelines is developed, using the recent advances made in the areas of lifeline earthquake engineering and probabilistic...
Structures Congress Abstracts 1990
Abstract only. The following themes are included: Rehabilitation and future challenges, Bridges, Earthquake engineering, Dynamic loads on structures, Metals and composite construction,...
Progress in Hydromechanics
The historical development of hydromechanics in the fifty years since the founding of the Hydraulics Division is reviewed. Rouse's 1938 text, Fluid Mechanics for Hydraulic Engineers, provided...
Surface Water Hydrology
