(The American Society of Mechanical Engineers (ASME), 2004)The 8th International Symposium on Gas-Liquid Two-Phase Flows took place during the ASME/JSME Joint Fluids Engineering Division Summer Meeting held July 6–10, 2003 at the Sheraton Waikiki Hotel, ... -
PANELIST COMMENTS ON: OPEN QUESTIONS AND NEW DIRECTIONS IN GAS-LIQUID FLOWS
(The American Society of Mechanical Engineers (ASME), 2004)Summaries of the ideas and discussion contributed by the panelists are presented in this article. Each panelist has contributed under a separate title in order to preserve the individuality of ... -
Measurement and Modeling of Propeller Cavitation in Uniform Inflow
(The American Society of Mechanical Engineers (ASME), 2004)An experimental and theoretical investigation on a cavitating propeller in uniform inflow is presented. Flow field investigations by advanced imaging techniques are used to extract quantitative ... -
Erratum: “An Experimentally Validated Model for Two-Phase Pressure Drop in the Intermittent Flow Regime for Circular Microchannels,” [Journal of Fluids Engineering, 2002, 124, pp. 205–214]
(The American Society of Mechanical Engineers (ASME), 2004)1. By convention, most of the equations in this paper treat pressure drop as a negative value. For consistency, the following equations should have the negative signs added as shown below: ... -
Modeling the Rapid Part of the Pressure-Diffusion Process in the Reynolds Stress Transport Equation
(The American Society of Mechanical Engineers (ASME), 2004)Modeling the pressure-diffusion process is discussed to improve the prediction of turbulent recirculating flows by a second moment closure. Since the recent DNS research of a turbulent recirculating ... -
Loss Reduction Using Riblets on a Supersonic Through-Flow Fan Blade Cascade
(The American Society of Mechanical Engineers (ASME), 2004)An experimental and computational study to determine the effects of riblets on the performance of the Supersonic Throughflow Fan (STF) cascade blades was performed. The cascade was tested in ... -
Secondary Flow Control Using Vortex Generator Jets
(The American Society of Mechanical Engineers (ASME), 2004)In this paper, results are presented of an experimental investigation into the effectiveness of vortex generator jets in controlling secondary flows in two-dimensional S-duct diffusers. The ... -
The Design of a New Flow Meter for Pipes Based on the Drag Force Exerted on a Cylinder in Cross Flow (Drag Force Flow Meter: DFFM)
(The American Society of Mechanical Engineers (ASME), 2004)It is shown how to design a new method (DFFM) of flow metering in pipes from basic principles. The method relies on the well known drag force on a cylindrical body and the force measurement ... -
A Stochastic Model for Gravity Effects in Particle-Laden Turbulent Flows
(The American Society of Mechanical Engineers (ASME), 2004)A stochastic model is presented for the prediction of the gravity effects on velocity and temperature fluctuations in turbulent flows laden with solid particles. Both temporal and spatial ... -
Momentum Flux in Plane, Parallel Jets
(The American Society of Mechanical Engineers (ASME), 2004)The evolution of the streamwise momentum flux for two turbulent, plane, parallel jets discharging through slots in a direction normal to a wall was studied both numerically and experimentally. ... -
On the Criterion for the Determination Transition Onset and Breakdown to Turbulence in Wall-Bounded Flows1
(The American Society of Mechanical Engineers (ASME), 2004)Starting from the basic conservation laws of fluid flow, we investigated transition and breakdown to turbulence of a laminar flat plate boundary layer exposed to small, statistically stationary, ... -
Large-Scale Disturbances and Their Mitigation Downstream of Shallow Cavities Covered by a Perforated Lid
(The American Society of Mechanical Engineers (ASME), 2004)Flow past cavities covered by perforated lids pose a challenging problem for design engineers. Kelvin–Helmholtz waves appear early in the separated shear layers above the perforations that quickly ... -
Wake Flow of Single and Multiple Yawed Cylinders
(The American Society of Mechanical Engineers (ASME), 2004)An experimental and computational study is performed of the wake flow behind a single yawed cylinder and a pair of parallel yawed cylinders placed in tandem. The experiments are performed for ... -
Entrainment by a Refrigerated Air Curtain Down a Wall
