Transient Fluid-Structure Interaction in a Control Valve
(The American Society of Mechanical Engineers (ASME), 1997)Numerical investigation on the interaction of a viscous incompressible fluid with a control valve is conducted by using the finite element method and Newmark approach. Variables including ... -
An Experimental Investigation Into the Breakdown of Low Reynolds Number Pulsed Flows at a Pipe Orifice
(The American Society of Mechanical Engineers (ASME), 1997)An experimental investigation into the behavior of pulsed vortex flows in water at a pipe orifice is outlined. An experimental apparatus is described whereby flow pulsations are generated using ... -
Near-Wall Modeling of Plane Turbulent Wall Jets
(The American Society of Mechanical Engineers (ASME), 1997)In most two-dimensional simple turbulent flows, the location of zero shear usually coincides with that of vanishing mean velocity gradient. However, such is not the case for plane turbulent ... -
A Finite-Element Study of Newtonian and Power-Law Fluids in Conical Channel Flow
(The American Society of Mechanical Engineers (ASME), 1997)A numerical study of Newtonian and shear-thinning fluids in high-speed, laminar flow through a conical channel is presented. Using a variety of cone-angles and Reynolds numbers on the order of ... -
A Reynolds Stress Function for Wall Layers
(The American Society of Mechanical Engineers (ASME), 1997)Data for the Reynolds stress near a wall are correlated by employing the theory of perturbation methods to form a composite expansion. This absorbs, to first order, the effects of Reynolds ... -
Strongly-Coupled Multigrid Method for 3-D Incompressible Flows Using Near-Wall Turbulence Closures
(The American Society of Mechanical Engineers (ASME), 1997)An efficient artificial compressibility algorithm is developed for solving the three-dimensional Reynolds-averaged Navier-Stokes equations in conjunction with the low-Reynolds number k-ω turbulence ... -
Assessment of Artificial Dissipation Models for Three-Dimensional Incompressible Flow Solutions
(The American Society of Mechanical Engineers (ASME), 1997)Various approaches for constructing artificial dissipation terms for three-dimensional artificial compressibility algorithms are presented and evaluated. Two, second-order accurate, central-differencing ... -
Design of Homologous Ram Pumps
(The American Society of Mechanical Engineers (ASME), 1997)The hydraulic ram pump was invented over 200 years ago but became obsolete with the availability of mains water. Ram pumps make use of a renewable energy resource and are environmentally ... -
Wavenumber Spectra of High Magnitude Wall Pressure Events in a Numerically Simulated Turbulent Boundary Layer
(The American Society of Mechanical Engineers (ASME), 1997)A method for conditionally sampling the spatial field of the wall pressure beneath a turbulent boundary layer in order to search for high magnitude events and calculate the corresponding ... -
Turbulent Wall-Pressure Fluctuations: A New Model for Off-Axis Cross-Spectral Density
(The American Society of Mechanical Engineers (ASME), 1997)Models for the distribution of the wall-pressure under a turbulent boundary layer often estimate the coherence of the cross-spectral density in terms of a product of two coherence functions. ... -
Aero-Thermodynamic Loss Analysis in Cases of Normal Shock Wave-Turbulent Shear Layer Interaction
(The American Society of Mechanical Engineers (ASME), 1997)Transonic-supersonic decelerating flow cases appearing in modern turbomachines are some of the most complex flow cases in fluid mechanics which also present practical interest. In the present ... -

The Case of the Singing Vortex
(The American Society of Mechanical Engineers (ASME), 1997)A relatively high amplitude, discrete tone is radiated from fully developed tip vortex cavitation under certain conditions. The phenomenon of the “singing vortex” was first reported by Higuchi ... -
Experimental Study of Turbulent Concentration Flow Field in the Wake of a Bluff Body
(The American Society of Mechanical Engineers (ASME), 1997)Experiments were conducted to determine the turbulent concentration field in the wake of a normal flat plate. Dye was introduced behind the plate as the tracer. The measurement of the dye ... -
