Flow Properties of Submerged Heated Effluents in a Waterway

AIAA Journal, 1972
An experimental and theoretical investigation has been undertaken to study the trajectory and growth of thermal effluents having a range of discharge velocities and temperatures. The discharge of an effluent into a waterway was mathematically modeled as a submerged jet injection process by using an integral method which accounts for natural fluid ...

Critical Submergence for Intakes in Open Channel Flow

Journal of Hydraulic Engineering, 1995
In this study, critical submergence for an air-entraining vortex at intakes in a uniform canal flow was investigated. The potential flow solution for the combination of a point sink and a uniform canal flow is available, and is known as Rankine's ovoids or half-bodies. This study was based on Rankine's ovoids.

Rotary gate: Submerged flow condition

Flow Measurement and Instrumentation, 2021
Abstract The rotary gate is a recently proposed gate for application in semicircular elevated irrigation networks. In this study, the hydraulics of rotary gate submerged flow was theoretically and experimentally investigated. Two approaches for estimating the submerged flowrate were considered, namely the stage-discharge based on the superposition ...

Hydroextraction: Flow in submerged cakes

AIChE Journal, 1957
AbstractFlow equations have been proposed for hydroextractor cakes wherein the pores are filled with moving liquid. These equations have been confirmed for the effect of each variable by use of different experimental techniques. The critical wetting rate has provided the most informative steady state, in which the cake is fed with liquid to maintain ...

Flow in submerged sewers with manholes

Urban Water, 2000
Abstract The energy loss at manholes in sewers increases when the latter are submerged. To quantify these losses a hydraulic model was built. The head losses could be reduced by fitting a perforated cover plate on top of the benches. Loss coefficients were determined under steady flow conditions.

Flow Through Submerged Orifices

Physics, 1935
From the measurements of F. E. Giesecke on the flow of liquids through submerged orifices two definite laws have been deduced. When the diaphragm is completely closed, the liquid flows backwards along the wall of the tube, and forward in a central vein, the radius of which has been calculated for laminar and turbulent flow. The theory by v.

Analysis of flow past submerged vanes

Journal of Hydraulic Research, 2000
Details of recently undertaken numerical study to analyze the physics of the flow past a submerged vane is presented. The numerical model solves the fully three-dimensional Reynolds-averaged Navier-Stokes equations in conjunction with the standard two-equation k-t turbulence closure. The governing equations are formulated in generalized boundary-fitted

Submerged Sluice Control of Stratified Flow

Journal of the Hydraulics Division, 1958
Results of study of gravity underflow control by means of submerged sluice; conditions established for maximum discharge from lower, heavier layer without withdrawal from lighter layer above; problem arose in connection with design of condenser water intake for Kingston steam plant of TVA.

Flow Characteristics of Submerged Jets

Transactions of the American Society of Mechanical Engineers, 1929
Abstract In this paper, which deals with submerged square-edged and chamfered short tubes or jets, the author shows by dimensional analysis and corroboratory experiment that the coefficient of discharge for geometrically similar jets is a function of the rate of discharge, the fluidity of the liquid, and the jet diameter.
