RISSeasonal Variations in Isoprene Emissions from a Boreal Aspen Forest
Publisher: American Meteorological Society
Abstract: The primary objective of this study was to understand the environmental and seasonal controls over isoprene emissions from a boreal forest ecosystem whose isoprene source came from trees of the same species and age. A ...
The Effect of Naturally Developing Roughness on the Mass Transfer in Pipes Under Different Reynolds Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The local mass transfer over dissolving surfaces was measured at pipe Reynolds number of 50,000, 100,000, and 200,000. Tests were run at multiple time periods for each Reynolds number using 203 mm diameter test sections ...
Effects of Surface Roughness and Bend Geometry on Mass Transfer in an S-Shaped Back to Back Bend at Reynolds Number of 200,000
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were performed to investigate the local development of roughness and its effect on mass transfer in an S-shaped bend at Reynolds number of 200,000. The tests were performed over four consecutive time periods ...
Measurement of Local Mass Transfer and the Resulting Roughness in a Large Diameter S Bend at High Reynolds Number
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The local mass transfer and the resulting roughness in a 203 mm diameter backtoback bend arranged in an Sconfiguration were measured at a Reynolds number of 300,000. A dissolving wall method using gypsum dissolution to ...
Stationary Planetary Waves Inferred from WINDII Wind Data Taken within Altitudes 90–120 km during 1991–96
Publisher: American Meteorological Society
Abstract: A climatology of stationary planetary waves (SPWs) in horizontal winds at latitudes 70°S?70°N and altitudes 90?120 km is obtained from Wind-Imaging Interferometer (WINDII) green line measurements in December?January and ...
Observed Oceanic Response over the Upper Continental Slope and Outer Shelf during Hurricane Ivan
Publisher: American Meteorological Society
Abstract: Hurricane Ivan passed directly over an array of 14 acoustic Doppler current profilers deployed along the outer continental shelf and upper slope in the northeastern Gulf of Mexico. Currents in excess of 200 cm s?1 were ...
Turbulent Diffusivity under High Winds from Acoustic Measurements of Bubbles
Publisher: American Meteorological Society
Abstract: reaking surface waves generate layers of bubble clouds as air parcels entrain into the upper ocean through the action of turbulent motions. The turbulent diffusivity in the bubble cloud layer is investigated by combining ...
Opposite Variability of Indonesian Throughflow and South China Sea Throughflow in the Sulawesi Sea
Publisher: American Meteorological Society
Abstract: ased on a high-resolution (0.1° ? 0.1°) regional ocean model covering the entire northern Pacific, this study investigated the seasonal and interannual variability of the Indonesian Throughflow (ITF) and the South China ...
Cost Estimates of Cellulosic Ethanol Production: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Increasing demands and concerns for reliable supply of liquid transportation fuels make it important to find alternatives to petroleumbased fuels. One such alternative is ethanol made from cellulosic biomass. Considerable ...
Nonlinear Time and Frequency Domain Methods for Multirow Aeromechanical Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An unsteady Navier–Stokes solution system for aeromechanical analysis of multiple blade row configurations is presented. A distinctive feature of the solver is that unified numerical methods and boundary condition ...
