RISFroude Number Scaling of Wind-Stress Coefficients
Publisher: American Meteorological Society
Abstract: Following the verification of the logarithmic nature of the wind profile and the establishment of a non-dimensional expression relating the shear velocity and surface roughness, a Froude number is proposed for scaling the ...
Aerosol Dynamics in the Near Field of Engine Exhaust Plumes
Publisher: American Meteorological Society
Abstract: A simulation methodology previously employed to study the effect of large- and small-scale turbulent mixing on gaseous chemistry in engine exhaust plumes has been extended in this study to investigate aerosol dynamics. An ...
Effects of Micro- and Macroscale Turbulent Mixing on the Chemical Processes in Engine Exhaust Plumes
Publisher: American Meteorological Society
Abstract: Turbulent mixing and chemical reactions in the near field of an engine exhaust jet plume have been investigated using a mixing model that explicitly incorporates both large- and small-scale turbulent mixing and the molecular ...
Static Wetting of a Liquid Droplet on a Soft Elastic Substrate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A refined spherical cap model, combined with an elastic foundation model for the elastic substrate, is proposed to study the static wetting of a liquid droplet on a soft elastic substrate. The strain energy of the substrate ...
Origin and Decay of Longitudinal Vortices in Developing Flow in a Curved Rectangular Duct (Data Bank Contribution)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Developing turbulent flow in a 90 deg curved duct of rectangular cross-section, and an aspect ratio of 6, was investigated. Mean-velocity and Reynolds-stress components were measured using a ...
Effects of Entrainment on Incapability of High Intensity Beam Drilling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of entrainment accompanying mass, momentum, and energy transport from the keyhole wall on keyhole collapse during highpowerdensity laser or electron beam drilling are theoretically and systematically investigated ...
Static Wetting of a Liquid Droplet on a Soft Elastic Substrate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A refined spherical cap model, combined with an elastic foundation model for the elastic substrate, is proposed to study the static wetting of a liquid droplet on a soft elastic substrate. The strain energy of the substrate ...
Thermomechanical Analysis of Pressure Vessels With Functionally Graded Material Coating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure vessels covered with overlaying layer or coating are widely applied due to its strong heat resistance, corrosion resistance, and loadcarrying capacity. However, limited work has been reported on investigating the ...
Secondary Flow and Entropy Generation of Laminar Mixed Convection in the Entrance Region of a Horizontal Square Duct
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow structure, heat transfer, and entropy generation characteristics in the entrance region of mixed convection under the effect of transverse buoyancy force are investigated numerically. Results are obtained for ...
Semianalytical Solution to Determine Minimum Safety Thickness of Rock Resisting Water Inrush from Filling-Type Karst Caves
Publisher: American Society of Civil Engineers
Abstract: A semianalytical solution to determine the minimum safety thickness of the rock resisting water inrush from filling-type karst caves was investigated. Mechanical analyses of the filling materials in karst caves located in ...
