RISSimilarity Relationships in the Marine Atmospheric Surface Layer for Terms in the TKE and Scalar Variance Budgets
Publisher: American Meteorological Society
Abstract: Measurements of the momentum, heat, moisture, energy, and scalar variance fluxes are combined with dissipation estimates to investigate the behavior of marine surface layer turbulence. These measurements span a wide range ...
Drag Reduction in Synthetic Seawater by Flexible and Rigid Polymer Addition Into a Rotating Cylindrical Double Gap Device
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible and rigid long chain polymers in very dilute solutions can significantly reduce the drag in turbulent flows. The polymers successively stretch and coil by interacting with the turbulent structures, which changes ...
Drag Reducing Flows by Polymer Solutions in Annular Spaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We analyze the use of water solutions of Xanthan Gum (XG) for drag reduction (DR) in annular spaces. We provide a direct quantitative comparison between the DR in an annulus and that in straight tubes. We can fairly compare ...
Drag Reduction by Polymers in Saline Nutrient Solutions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drag reduction (DR) by polymers has several industrial applications, and it has also shown to produce beneficial effects on blood circulation and may represent a way to treat cardiovascular disorders. Concerning medical ...
Friction Coefficients for Bingham and Power-Law Fluids in Abrupt Contractions and Expansions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Industrial processes with non-Newtonian fluids are common in many segments such as petroleum, cosmetic, and food industries. Slurries, emulsions, and gas–liquid dispersions are some examples with industrial relevance. When ...
Inertial-Dissipation Air-Sea Flux Measurements: A Prototype System Using Realtime Spectral Computations
Publisher: American Meteorological Society
Abstract: A prototype system for the measurement and computation of air?sea fluxes in realtime was tested in the Humidity Exchange Over the Sea (HEXOS) main experiment, HEXMAX. The system used a sonic anemometer/thermometer for wind ...
Turbulence Sensor Dynamic Calibration Using Real-Time Spectral Computations
Publisher: American Meteorological Society
Abstract: The integration of plug-in Fast Fourier Transform (FFT) boards in data acquisition computers allows a considerable development in the dynamic calibration of turbulence sensors. The spectral transfer function of a fast and ...
Use of Spaceborne Synthetic Aperture Radar Imagery of the Sea Surface in Detecting the Presence and Structure of the Convective Marine Atmospheric Boundary Layer
Publisher: American Meteorological Society
Abstract: Two distinct backscatter regimes are seen on a European remote sensing satellite ERS-1 C-band (5.6 cm) synthetic aperture radar (SAR) image of the sea surface during a time of fair synoptic-scale weather conditions. One ...
Measurement of Temperature Spectra by a Sonic Anemometer
Publisher: American Meteorological Society
Abstract: The response of a Kaijo Denki DAT 300 ultrasonic anemometer-thermometer is analyzed with respect to temperature and vertical velocity. The effects of the emitting-receiving cycle of the transducer array on w, T, and CowT ...
Bulk Parameterization of Air–Sea Fluxes: Updates and Verification for the COARE Algorithm
Publisher: American Meteorological Society
Abstract: In 1996, version 2.5 of the Coupled Ocean?Atmosphere Response Experiment (COARE) bulk algorithm was published, and it has become one of the most frequently used algorithms in the air?sea interaction community. This paper ...
