Turbulent Entrainment in Buoyant Jets and Plumes

*The behavior of turbulent buoyant jets in uniform density environments is found to be governed by an entrainment function and buoyancy function, both of which are functions of the local...*

Bed Scour at End-Dump Channel Constrictions

*One method of constricting a channel is by end-dumping loose rockfill from one or both banks. This study is concerned with bed scour that occurs around the leading face and downstream...*

Wave Forces on Submerged Objects of Symmetry

*Stokes' linear irrotational wave theory is employed to obtain expressions for wave forces on submerged objects of symmetry, e.g., a hemisphere or a sphere, a horizontal halfcylinder...*

Spatially Varied Flow over Side-Weirs

*An experimental investigation of the flow over sharp edged side-weirs in rectangular channels is reported. The experiments cover subcritical and supercritical flow regimes with weirs of...*

Gradually Varying Two-Layer Stratified Flow

*The basic equations of stratified flow in fiords are outlined. The mechanism of entrainment is physically explained, and the entrainment is then related to the shear stress at the interface...*

Oil Booms in Tidal Currents

*The oil capacity of a boom deployed in U-shape in a current depends primarily on the densimetric Froude number, with a critical Froude number above which the boom holds no oil, and an...*

Drag Coefficient of Cylinders in Turbulent Flow

*The effects of free-stream turbulence on the drag coefficient of a circular cylinder were investigated experimentally in an air duct. The experiments were performed over a range of Reynolds...*

Reattaching Flow Downstream of Leaf Gate

*Measurements have been made of the mean velocities and wall pressures downstream of a blockage simulating a partially closed leaf gate, and the extent of recirculation has been formed....*

Dynamics of Contained Oil Slicks

*An oil slick contained on the surface of a flowing stream may be divided into two zones of influence; a frontal region where dynamic forces are dominant and a viscous zone where viscous...*

Boundary Layer Effects on Hydraulic Jump Location

*The rate of displacement of the toe of a hydraulic jump along a channel with respect to change in tailwater elevation is defined as the position sensitivity of the jump. The steady flow...*

Appearance of Unstable Buoyant Jet

*The flow of a turbulent vertical plume in a stagnant ambient fluid of uniform density was examined theoretically and experimentally. It was shown that a real solution to the equations...*

Turbulence Effects on Drag of Sharp-Edged Bodies

*Contrary to popular opinion, wind tunnel tests showed that the drag coefficient of angular shaped bodies is significantly affected by the intensity of the free stream turbulence. For some...*

Pipelining of Low-Centration Sand-Water Mixtures

*The present study deals with critical deposit velocity V*

_{C}, defined as the velocity at which particles begin to settle from the carrying medium and...Effects of Inflow Condition on Hydraulic Jump

*The particular aspect of the jump phenomenon considered in the paper concerns the condition of inflow, i.e., the state of flow development of the supercritical stream. Based on an unconventional...*

Supercritical Flow over Sills at Incipient Jump Conditions

*A laboratory investigation has been conducted to study the conditions mainly responsible for the stabilization and prediction of the hydraulic jump in a rectangular, horizontal-bed channel...*

Orifice Losses for Laminar Approach Flow

*In all, 25 orifices are studied which include sharp-edged concentric, eccentric and segmental orifices, quadrant-edged concentric orifices and square-edged long orifices. The β ratio (ratio...*

Brink Depth for Trapezoidal Broad-Crested Weir

*Brink depth characteristics include the relationship between brink depth (y*

_{o}) and critical depth for parallel flow (y_{c});...Onset of Instability of Power-Law Fluid in Couette Flow

*The critical Reynolds numbers at the onset of instability of a Newtonian and a power-law fluid, respectively, in the annulus between two coaxial cylinders, with the inner cylinder rotating...*
