Entrained Air in Linearly Accelerated Water Flow that
The reviewed theoretical literature has suggested that a gas bubble introduced to a linearly accelerated liquid flow will soon lead the flow, and ultimately approach an equilibrium state...

Air Retained in Pool by Plunging Water Jet
The volume of air retained in a receiving pool by plunging water jets of different characteristics was measured using an air concentration probe. The effect of jet diameter, height of...

Offshore Water Intakes Designed to Protect Fish
The engineering design and biological effectiveness of five design concepts for fish protection at offshore intakes are examined. Velocity cap intakes entrap large quantities of fish at...

Sensitivity of the Prych-Davis-Shirazi Model

Use of Porous Dike to Reduce Entrainment and Entrapment in Power Plant Cooling Water Systems

Collie River Underflow into the Wellington Reservoir
Field data gathered from a Western Australian reservoir are used to obtain an estimate for the entrainment coefficient of the underflowing river. By the use of a steady normal flow theory,...

Heat Recirculation Induced by Thermal Diffusers
A unidirectional multiport thermal diffuser discharges large quantities of condenser cooling water in the form of a line of turbulent heated jets near the bottom of the receiving waterbody....

Contractors and Production of Durable Air-Entrained Concrete
The contractor-modification of air-entrained concrete mix proportions and production practices to suit actual construction conditions is covered in detail. The effects of alternate mix...

Air-Water Flow in Coarse Granular Media
Air may be entrained in the flow in porous shore structure under wave action. Three conceptual models for two-phase flow in ducts have been adapted to describe flow in coarse granular...

Air Entrainment in Radial Flow Towards Intakes
The aim of this paper was to understand clearly the role of the different parameters on vortex formation. A study was made where the vanes for circulation are radial and thus the approach...

Wave Entrainment of Sediment from Rippled Beds
An experimental investigation was conducted with an oscillatory flow water tunnel to elucidate the mechanism of sediment entrainment by periodic fluid motion past rippled beds. The instrumentation...

Mean Behavior of Buoyant Jets in a Crossflow
A general theory to predict time-average trajectories and dilutions for turbulent buoyant jets in a crossflow is presented. The flow is analyzed by presenting simplified descriptions of...

Flow Pattern Control by Entrainment Regulation
A technique for controlling the flow to a vortex zone trapped between the top of a shallow submerged slot outlet, the free surface, and two lateral wing-walls is examined experimentally...

Entrainment and Drag Forces of Deflected Jets
Experiments were carried out on a round turbulent jet with a Reynolds number of 2x105 discharged perpendicularly into crossflows in a wind tunnel....

Air-Entrainment in High Head Gated Conduits
For the successful operation of high head gated conduits, adequate supply of air is of paramount importance. However, no dependable solution is yet available to determine the required...

Submerged Buoyant Jets in Quiscent Fluids
An integral-type analysis is developed for submerged buoyant jets discharged horizontally into quiescent homogeneous fluids. Equations for conservation of volume flux, buoyancy flux, and...

Effect of Wind Stress on Stratified Deep Lake
The basic equations for wind-driven flows in deep two-layered lakes are outlined. The deepening of the upper layer due to entrainment of more dense water from the lower layer is explained...

Jet Discharge into a Stratified Reservoir
An experimental investigation of the flow induced by a line jet in a linear-density stratified reservoir fluid is reported. Both buoyant and nonbuoyant jets were discharged into the stratified...

Improved Fish Protection at Intake Systems
Experimental studies in the diversion and removal of fishes entrained in cooling water flow, and in entrainment reduction at offshore intake structures, were done with coastal marine species...

Air Entrainment in Surface Rollers
Studies indicate that surface rollers are well suited as hydraulic aeration devices for water quality enhancement. An important indicator concerning the efficiency of such devices is the...
