High-Order Time-Integration Schemes with Explicit Time-Splitting Methods
Publisher: American Meteorological Society
Abstract: New high-order time-integration schemes for fully elastic models are presented. The new schemes, formulated using the Richardson extrapolation that employs leapfrog-type schemes, can give a good performance for linear model ...
Hydrodynamic Damping on Flexible Cylinders in Sheared Flow
Publisher: American Society of Civil Engineers
Abstract: The role of hydrodynamic sources of damping in regulating the flowinduced vibration response of flexible cylinders has frequently been a source of disagreement between investigators in the field. A hydrodynamic damping ...
Effect of Machining Processes on the Fatigue Strength of Hardened AISI 4340 Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of two finishing processes, namely, cutting and grinding, on the fatigue strength of hardened AISI 4340 steel was investigated. Three sets of flat tensile specimens were prepared by ...
A Numerical Modeling Study of Mesoscale Cyclogenesis to the East of the Korean Peninsula
Publisher: American Meteorological Society
Abstract: Numerical simulations and the analysis of observational data are employed to understand the mesoscale cyclogenesis in a polar airstream that occurred over the sea to the east of the Korean peninsula on 28?29 January 1995. ...
Improvement of AERI T/q Retrievals and Their Validation at Anmyeon-Do, South Korea
Publisher: American Meteorological Society
Abstract: n Atmospheric Emitted Radiance Interferometer (AERI), which measures downwelling radiances, has been in operation at Anmyeon-do, South Korea, since June 2010. Temperature and moisture (T/q) profiles with high temporal and ...
A Snow-Ratio Equation and Its Application to Numerical Snowfall Prediction
Publisher: American Meteorological Society
Abstract: This study 1) presents a logistic regression equation of the snow ratio (SR) for use in a conversion of numerically predicted precipitation amounts into snowfall depths and 2) examines the quality of snowfall-depth forecasts ...
Rotordynamic Performance of an Oil-Free Turbo Blower Focusing on Load Capacity of Gas Foil Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engineered design of modern efficient turbomachinery based on accurate model predictions is of importance as operating speed and rate power increase. Industrial applications use hydrodynamic fluid ...
Effects of Mesh Density on Static Load Performance of Metal Mesh Gas Foil Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Metal mesh materials have been used successfully in vibration isolators and bearing dampers due to their superior friction or hysteresis damping mechanism. These materials are formed to metal ...
Coupling Rock-Fracture Propagation with Thermal Stress and Fluid Flow
Publisher: American Society of Civil Engineers
Abstract: This paper describes the theory behind a recent extension of a two-dimensional (2D) boundary-element code,
