Navier-Stokes Simulation of the Flow Around an Airfoil in Darrieus Motion
(The American Society of Mechanical Engineers (ASME), 1994)In order to study the dynamic stall phenomenon on a Darrieus wind turbine, the incompressible flow field around a moving airfoil is simulated using a noninertial stream function-vorticity ... -
Flow Patterns of Falling Liquid Film Observed Near an Obstacle
(The American Society of Mechanical Engineers (ASME), 1994)The purpose of this study is to investigate the flow patterns of a falling liquid film as observed near an obstacle on a flow channel. In this report, a bend on the channel was chosen as ... -
Unsteady Flow in Diffusers
(The American Society of Mechanical Engineers (ASME), 1994)The flow in a diffuser is unsteady in the range of optimum pressure recovery; diffusers can therefore be a major source of noise in pipework systems. A theory is developed to predict the ... -
Computational Study of Resonance Suppression of Open Sunroofs
(The American Society of Mechanical Engineers (ASME), 1994)A 2-D computational study of flow over a fully open sunroof of a car with a passenger compartment has been done on a scalar workstation. The critical velocity for resonance in the passenger ... -
Effect of Selective Modification of Turbulence on Two-Equation Models for Particle-Laden Turbulent Flows
(The American Society of Mechanical Engineers (ASME), 1994)The effect of selective modification of turbulence by particles on K–ε models for dilute two-phase flows has been evaluated using data from direct numerical simulation of particle-laden isotropic ... -
The Wave-Thinning and Breakup of Liquid Sheets
(The American Society of Mechanical Engineers (ASME), 1994)In this study, the radially thinning liquid sheets formed by a simple splash plate nozzle were investigated. These sheets, observed using high-speed video and 16 mm photography, were found to ... -
Recirculation in an Annular-Type Jet Pump
(The American Society of Mechanical Engineers (ASME), 1994)For some annular-type jet pump applications, it is important to avoid formation of a recirculation zone in the mixing region. The goals of this research were to find (i) when recirculation ... -
Particle Mixing and Volumetric Expansion in a Vibrated Granular Bed
(The American Society of Mechanical Engineers (ASME), 1994)The present experiments are an investigation of the expansion and mixing that occur in a horizontal bed of particles subjected to vibrational accelerations in the direction parallel to gravity. ... -
Development of Prototype Pump Using a Vibrating Pipe With a Valve
(The American Society of Mechanical Engineers (ASME), 1994)Tests were conducted on a prototype pump which has an extremely simple structure and excellent controllability. Its structural and hydrodynamic features are different from those of previous ... -
Remarks on Snow Cornice Theory and Related Experiments With Sink Flows
(The American Society of Mechanical Engineers (ASME), 1966)A review is made of Ringleb’s theory on snow cornice-like flows and of the published, unsuccessful attempts at experimental verification. Arguments are presented which render the theory an ... -
Hydrodynamics and Erosion Modeling of Fluidized Bed Combustors
(The American Society of Mechanical Engineers (ASME), 1994)Hydrodynamics and erosion of Fluidized Bed Combustors (FBCs) containing tubes have been analyzed through the use of the hydrodynamic model, which has been developed at New York University, ... -
On the Dynamics of Flow Structure Development in an Excited Plane Jet
(The American Society of Mechanical Engineers (ASME), 1994)Coherent structure dynamics in the developing region of a plane jet under acoustic excitation is studied experimentally by means of hot-wire measurements and smoke-wire flow visualization. The ... -
On the Compressible Flow Losses Through Abrupt Enlargements and Contractions
(The American Society of Mechanical Engineers (ASME), 1994)The well-known structure of incompressible flow through abrupt enlargements and contractions is applied to the subsonic compressible flow through the same area change. Using the basic system of ... -
Secondary Flows in an Incompressible Fluid of Varying Density in a Rotating Reference Frame
