Turbulence Attenuation by Small Particles in Simple Shear Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with the influence of a dispersed phase on carrier flow turbulence. The carrier flow is assumed to be a simple homogeneous shear, in which the fluid Reynolds stress ...
Robust Active Vibration Control of a Bandsaw Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical study of a vibrating bandsaw blade is presented. The blade is modeled as a plate translating over simply-supporting guides. Gyroscopic effects due to the blade’s axial motion as ...
Performance Characteristics of Centrifugal Slurry Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of two centrifugal slurry pumps has been reported for three solid materials having different particle size distribution (PSD) in terms of head, capacity, and power characteristics. ...
Fuzzy Approaches to Evaluation in Engineering Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As variables in the design evaluation stage are imprecise (fuzzy), tools, such as fuzzy set theory, should be used. This paper presents several fuzzy approaches to design evaluation. Weights ...
Subspace-Based System Identification for an Acoustic Enclosure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is aimed at identifying a dynamical model for an acoustic enclosure, a duct with rectangular cross section, closed ends, and side-mounted speaker enclosures. Acoustic enclosures are ...
Effects of Elevated Free-Stream Turbulence on Actively Controlled Separation Bubble1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of elevated free-stream turbulence (FST) on natural and periodically excited separation bubbles were examined experimentally at low Reynolds numbers. The bubble was formed at the ...
Some Aspects of the Aerodynamics of Gurney Flaps on a Double-Element Wing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gurney flaps of different heights have been fitted to a generic double-element wing, and the effects at two typical flap angles have been observed using force and pressure measurements, and ...
An Analytical Solution for Incompressible Flow Through Parallel Multiple Jets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical model of multiple jet flow is introduced based on the thin shear layer theory. The analytical solution has been obtained by using Prandtl’s mixing length hypothesis. The results ...
Numerical Simulation on the Flow Structure Around the Injection Nozzles for Pneumatic Dimensional Control Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical simulation on the airflow exiting from a nozzle in a pneumatic dimensional control system has been conducted using computational fluid dynamics code FLUENT (V. 4.3), which solves ...
Mixing Characteristics of Axisymmetric Free Jets From a Contoured Nozzle, an Orifice Plate and a Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The differences in mixing performance between axisymmetric turbulent jets issuing from three common types of nozzle, viz. a contoured (or smooth contraction) nozzle, a sharp-edged orifice and a ...
