Flow through a submerged nozzle

Journal of Spacecraft and Rockets, 1995
Measurements of mean and fluctuating velocity components are obtained with refractive-index-matching laser velocimetry in a submerged nozzle representative of thrust-vectoring nozzles in solid rocket motors. The approaching flow has a structure similar to that approaching a sudden contraction, but is affected by the large annular recirculation bubble ...

Effect of Baffles on Submerged Flows

Journal of Hydraulic Engineering, 1995
This paper introduces the concept of a submerged hydraulic jump being used for energy dissipation. A baffle wall is used to produce a stable deflected surface jet, thereby deflecting the high-velocity supercritical stream away from the bed to the surface. Based on a series of experiments, a diagram was developed that predicts the conditions under which

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 ...

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 ...

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.

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 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.

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.

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
