RISNine Decades of Fluid Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As the ASME Division of Fluids Engineering celebrates its 90th Anniversary, I make a broadbrush sweep of progress in the field of fluid mechanics during this period. Selected theoretical, numerical, and experimental advances ...
Bond Graph Modeling of a Two Stage Pressure Relief Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examined the use of bond graphs for the modeling and simulation of a fluid power system component. A new method is presented for creating the bond graph model, based upon a previously developed mathematical ...
Modeling and Simulation of the Steady State and Transient Performance of a Three Way Pressure Reducing Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with modeling and simulation of a class of threeway pressure reducing valves. The study aims to point out the peculiarities of function and operation of this class of valves in the steadystate and transient ...
Surface Dynamics of Observed Maritime Fronts
Publisher: American Meteorological Society
Abstract: The problem of establishing the important mechanisms and processes in surface fronts is examined. It is shown that boundary layer processes may modify the details of frontal dynamics near the surface and that at the same ...
The Lowest Mode of Oceanic Convection
Publisher: American Meteorological Society
Abstract: The assumption that the Antarctic polar front is a quasi-material frontal surface that separates the Antarctic from the warm ocean gives an estimate of 8 cm per year of upwelling and 0.4 cm2 s?1 of vertical diffusivity in ...
Visualization Techniques for Unsteady Flows: An Overview
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this article is to review some of the novel flow visualization techniques that are particularly suited for studying unsteady flows. While many of these techniques are equally ...
The Use of the Dye-Layer Technique for Unsteady Flow Visualization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The unsteady flow around three-dimensional lifting surfaces undergoing a harmonic pitching motion was studied in a towing tank using the dye-layer technique. Different color fluorescent dyes were ...
Stress Distribution in the Red Sea and in the Gulf of Aqaba
Publisher: American Meteorological Society
Abstract: A scale analysis indicates that the cross-axial component of the vorticity equation reduces to a two-term expression: a buoyancy gradient term and a term involving the depth-derivative of the shear stress. We have computed ...
The Response of Elastic and Viscoelastic Surfaces to a Turbulent Boundary Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The unstable response of elastic and viscoelastic surfaces to a turbulent boundary layer was experimentally investigated in an 18-m towing tank. The compliant surface deformation was measured ...
The Fluid Mechanics of Microdevices—The Freeman Scholar Lecture
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Manufacturing processes that can create extremely small machines have been developed in recent years. Microelectromechanical systems (MEMS) refer to devices that have characteristic length of less ...
