Comparison of Methods Analyzing Bifurcation and Hunting of Complex Rail Vehicle Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stability assessment is an important task in the mechanical design of railway vehicles. For a detailed model of a railway passenger coach, the hunting behavior depending on the running ...
Turbulence Spectra and Dissipation Rates in a Wind Tunnel Model of the Atmospheric Convective Boundary Layer
Publisher: American Meteorological Society
Abstract: A model of the atmospheric convective boundary layer (CBL) is realized in the thermally stratified wind tunnel of the Institute of Hydrology and Water Resources, University of Karlsruhe. Further experimental results from ...
Influence of Force Field Direction on Pressure Sensors Calibrated at Up to 12,000 g
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The measurement of pressure within both stationary and rotating frames of reference is a fundamental requirement when studying the flow field through turbomachinery blading. Measurement of pressure ...
Heat Balance of the Upper Ocean under Light Winds
Publisher: American Meteorological Society
Abstract: Measurements of the components of the heat balance of the upper 30 m of the ocean were made in the Bermuda area in August and September 1974. The quantities measured included surface downwelling and underwater downwelling ...
The Effects of Clouds on the Diurnal Variation of Underwater Irradiances on Horizontal Surfaces
Publisher: American Meteorological Society
Abstract: Measurements of underwater downwelling D, underwater upwelling U, both at 5 m, and surface down-welling irradiance I were taken over most of a 5-day period in August and September 1974 south and west of Bermuda. On clear ...
Laboratory Vortices in Rotating, Sheared Flow
Publisher: American Meteorological Society
Abstract: BY Placing a small convective source (electrical heater) in a rotating, vertically sheared, stratified flow in a rotating annulus, a well-organized vortex flow is generated. A qualitative description of the flow is given. ...
Satellite-Observed Reflectance of Snow and Clouds
Publisher: American Meteorological Society
Abstract: The effects of snow and cloud cover on bidirectional reflectance were examined using visible radiation (0.5?0.7 ?m) data measured by NOAA polar orbiting satellites between June 1974 and February 1978. Reflectances resulting ...
Offshore Decommissioning Cost Estimation in the Gulf of Mexico
Publisher: American Society of Civil Engineers
Abstract: Decommissioning offshore structures represents the end of the production life cycle, when wells are plugged and abandoned, infrastructure is removed, and the site is remediated and cleared of debris. Decommissioning ...
Heat Transfer by Symmetrical Rotating Annulus Convection
Publisher: American Meteorological Society
Abstract: Results of heat transfer measurements in a differentially heated annulus of fluid for both the non-rotating and rotating cases are given. (In the latter case the flow is in the upper symmetric regime.) In all cases the ...
Modeling the Transport of Fuel Mixture Perturbations and Entropy Waves in the Linearized Framework
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new method is introduced to model the transport of entropy waves and equivalence ratio fluctuations in turbulent flows. The model is based on the Navier–Stokes equations and includes a transport equation ...
