Prediction of the Flow Around an Airfoil Using a Reynolds Stress Transport Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A second-moment R eynolds S tress T ransport M odel (RSTM) is used in the present work for computing the flow around a two-dimensional airfoil. An incompressible SIMPLEC code is used, employing ...
Some Turbulence and Wind Variability Observations in the Lee of Mountain Ridges
Publisher: American Meteorological Society
Abstract: A field of turbulence and space and time wind variability in the lee of a ridge line is observed with double theodolite wind data. It is shown that the most turbulent areas occur above the lee slope and are associated with ...
Source Flux Corrections in Analytical Vapor Plume Models
Publisher: American Meteorological Society
Abstract: To derive analytical formulas for the rise and growth of a buoyant moist plume, it is necessary to introduce the Boussinesq and bent-over plume assumptions into the conservation equations. It is suggested that similar ...
Low-Reynolds Number Turbulence Models: An Approach for Reducing Mesh Sensitivity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents a new near-wall treatment for low-Reynolds number (LRN) turbulence models that maintains accuracy in ‘coarse’ mesh predictions. The method is based on a thorough examination ...
Low-Temperature Solar Thermal Systems: An Untapped Energy Resource in the United States
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solar energy to heat water, to warm buildings and to provide low temperature heat for industry and agriculture is a well understood technology. Of these applications, solar hot water is the ...
Applicability of Uniform Heat Flux Nusselt Number Correlations to Thermosyphon Heat Exchangers for Solar Water Heaters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: correlations for these tube-in-shell heat exchangers were previously developed in Dahl and Davidson (1998) from data obtained in carefully controlled experiments with uniform heat flux at the tube walls. The data presented...
A Survey of One Class of 7-Jointed Serially Connected Robots: Type-Synthesis to Obtain Controllably Dexterous Workspace
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A type-synthesis process, which is based on screw theory and geometry, is developed to identify certain robots, each of which can provide controllably dexterous workspace of a tool-point. The ...
