Mixing Characteristics of a Transitional Stratified Two-Layer Flow
Small scale structures in a stably stratified two-layer flow are investigated. The flow configuration has the initial velocity interface displaced with respect to the density interface....

An Experimental Study of Bivalve Siphonal Jets in a Turbulent Boundary Layer Crossflow
We conducted experiments in a laboratory flume to study the interaction of bivalve siphonal jets with the turbulent boundary layer which forms in the benthic region of shallow estuaries....

Fluid Mechanics Aspects of Ocean Outfalls
Prediction of the environmental effects of ocean outfalls requires understanding of some complex fluid mechanical phenomena. These include the dynamics of merging plumes in flowing, density-stratified...

Analysis of Pulsing Phenomenon in Viscous Debris Flow
Pulsing motion is the main pattern of viscous debris flow. Results of study on hyperconcentrated flow are briefly illustrated in this paper. By referring study results of hyperconcentrated...

Turbulent Velocity Flutuations in Natural Rivers
The longitudinal and transverse components of flow velocity, as well as the normal and tangential stresses, must be expected to fluctuate with time and space when flow at a high Reynolds...

Chatuge Hydroproject Aerating Infuser Physical Model Study
The Tennessee Valley Authority is investigating the feasibility of a dual purpose reregulation and aeration weir to increase the dissolved oxygen in water releases and to provide continuous...

Parameterization of Turbulence for Three-Dimensional Circulation Modeling
Estuarine circulation are driven by the actions of tide, wind, and density gradients associated with saline ocean water and fresh riverine water, and are also influenced by the complex...

Mixing Character and Meandering Mechanism of a Plane Jet Bounded in a Shallow Water Layer
A plane jet in a shallow water layer is characterized by the jet width b1/2 much larger than the water depth h at large downstream distances x/h...

A Diffusion Hydrodynamic Model of a Shallow Estuary: Verification
Many of the hydrodynamic models used for estuary tidal flows and storm surges are based on two two-dimensional hydrodynamic equations which are obtained form the full three-dimensional...

Diffusion of Radionuclides in Compacted Bentonite

Aspects of Parallel Processing in Reservoir Simulation
Vectorization techniques have proved to be extremely effective for large-scale reservoir simulations. Parallel capabilities hold even greater potential for these enormous problems. Domain...

On the Diffusional Stress Transmission
A probabilistic diffusional mechanism for the propagation of intergranular forces has been formulated as a set of three mathematical assumptions. The equilibrium equations are complemented...

Turbulence, and Energy Loss, at Combining Pipe Junctions
Efforts to measure and describe the loss of energy at 90° sharp-edged junctions are described. The work is focussed on energy losses at discharge and area ratios for which there are no...

General Mechanism of Turbulence
By considering the vortex structures of turbulence and using the concept and theory of the pulsative convection and diffusion of instantaneous vorticity in a viscous fluid motion, the...

Influence of Gas Phase Turbulence on the Transport of Particles
An interesting and perhaps unexpected flow feature characterizing the transport of a gas-solid suspension in a vertical duct is the radial nonuniformity of particles over the tube cross-section....

Very Low Frequency Radio Astronomy from Lunar Orbit
This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy...
