RISStructure and Evolution of a Possible U.S. Landfalling Tropical Storm in 2006
Publisher: American Meteorological Society
Abstract: A tropical disturbance made landfall near Morehead City, North Carolina, on 27 June 2006. Surface observations, Air Force reconnaissance, and Doppler velocity data suggest that the disturbance had a closed surface circulation ...

A Numerical Investigation of the Potential Effects of Aerosol-Induced Warming and Updraft Width and Slope on Updraft Intensity in Deep Convective Clouds
Publisher: American Meteorological Society
Abstract: AbstractThe effects of aerosol perturbations on deep convective clouds have received considerable attention in the recent literature, especially from a modeling perspective. The published responses in precipitation amount ...
Estimating Vertical Motion Profile Top-Heaviness: Reanalysis Compared to Satellite-Based Observations and Stratiform Rain Fraction
Publisher: American Meteorological Society
Abstract: method for representing geographic variability in vertical motion profile top-heaviness in reanalysis data is introduced. The results from this method are compared to a satellite-based method for estimating top-heaviness ...
Effect of Strain History and Mixture Proportions on Early-Age Cement Paste and Mortar Stress Relaxation
Publisher: ASCE
Abstract: The influence of sand particles, aging, and water–cement (w/c) ratio on the viscoelastic relaxation modulus of cement paste and mortars was measured at early ages (1–28 days). Furthermore, the relaxation modulus ...
Utilization of Silica Fume to Stabilize the Dispersion of Carbon Nanofilaments in Cement Paste
Publisher: American Society of Civil Engineers
Abstract: The incorporation of carbon nanofilaments in cementitious materials has been researched extensively in the past decade. However, the poor dispersibility of these filaments remains a hurdle to harnessing their exceptional ...
A Computational Study of Torque and Forces Due to Compressible Flow on a Butterfly Valve Disk in Mid-stroke Position
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ability to accurately predict the aerodynamic torque and lift and drag forces on a 2-D model of a 0.18 aspect ratio biconvex circular-arc disk operating in a compressible flow using ...
The Sensitivity of a Numerically Simulated Idealized Squall Line to the Vertical Distribution of Aerosols
Publisher: American Meteorological Society
Abstract: hanges in the aerosol number concentration are reflected by changes in raindrop size and number concentration that ultimately affect the strength of cold pools via evaporation. Therefore, aerosol perturbations can potentially ...
Flow Boiling Dynamics of Water and Nanofluids in a Single Microchannel at Different Heat Fluxes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The preferable cooling solution for microelectronic systems could be forced flow boiling in micro heat exchangers. Nanoparticle deposition affects nucleate boiling via alteration of surface roughness, capillary wicking, ...
Bump Type Foil Bearings and Flexure Pivot Tilting Pad Bearings for Oil Free Automotive Turbochargers: Highlights in Rotordynamic Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Oilfree turbochargers (TCs) require gas bearings in compact units of enhanced rotordynamic stability, mechanical efficiency, and improved reliability with reduced maintenance costs compared with oillubricated bearings. ...
