RISDetached Eddy Simulation Simulation of Asymmetrical Flow in a High Pressure Diesel Injector
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent experiments have shown that the lateral motion of a high pressure injector needle can lead to significant asymmetrical flow in the sac and asymmetric spray pattern in the combustor, which in turn degrades the ...
Eddies in the Labrador Sea as Observed by Profiling RAFOS Floats and Remote Sensing
Publisher: American Meteorological Society
Abstract: Data from profiling RAFOS floats, TOPEX/Poseidon altimetry, and the alongtrack scanning radiometer (ATSR) aboard ERS-1 have been used to describe the spatial and seasonal patterns of eddy variability in the Labrador Sea. ...
Aircraft Measurements of Ageostrophic Winds
Publisher: American Meteorological Society
Abstract: The Wyoming King Air flew along the 319.5-K isentropic surface and measured ageostrophic winds in the exit region of a polar jet on 8 March 1992. Ageostrophic winds were derived from 1) differences between geostrophic and ...
An Alternative Hypothesis for the Origin of the “Mediterranean” Salt Lens Observed off the Bahamas in the Fall of 1976
Publisher: American Meteorological Society
Abstract: A hypothesis is presented that the original salt lens, or ?meddy,? observed off the Bahamas in the fall of 1976 may have been formed, not near the Mediterranean outflow, but instead in the vicinity of the northwest corner ...
A Meddy off Cape St. Vincent. Part I: Description
Publisher: American Meteorological Society
Abstract: A meddy, an eddy formed from Mediterranean source water, was surveyed in detail with two types of expendable profilers and a CTD instrument. The muddy comprised two distinct, vertically aligned tenses with a combined ...
Critical Behavioral Assumptions in Evacuation Time Estimate Analysis for Private Vehicles: Examples from Hurricane Research and Planning
Publisher: American Society of Civil Engineers
Abstract: The computation of evacuation time estimates (ETEs) for communities threatened by hurricanes requires analysts to develop sophisticated models of evacuation flows and significant progress has been made in this area over ...
Politics of Hazard Mitigation
Publisher: American Society of Civil Engineers
Abstract: The formulation, adoption, and implementation of mitigation measures is an intensely political process that hazards professionals need to understand if they are to be effective in reducing community hazard vulnerability. ...
Assessing Community Impacts of Natural Disasters
Publisher: American Society of Civil Engineers
Abstract: Research on the community impacts of natural disasters has yielded a wide variety of findings, but no coherent model of the process by which hazard agent characteristics produce physical and social impacts. This article ...
Tsunami Preparedness on the Oregon and Washington Coast: Recommendations for Research
Publisher: American Society of Civil Engineers
Abstract: This study sought to identify the research that is needed to improve tsunami emergency preparedness in the Pacific Northwest. A search of the archival literature yielded very few journal articles and technical reports on ...
