RISUnderstanding the Distribution of Multimodel Ensembles
Publisher: American Meteorological Society
Abstract: When analyzing multimodel climate ensembles it is often assumed that the ensemble is either truth centered or that models and observations are drawn from the same distribution. Here we analyze CMIP5 ensembles focusing on ...
Bimodality of the Planetary-Scale Atmospheric Wave Amplitude Index
Publisher: American Meteorological Society
Abstract: The evidence for multiple flow regimes in the planetary-scale atmospheric wave amplitude index (WAI) is studied using the 56 winters from the NCEP reanalysis data. The regimes are identified by bimodality in the probability ...
Nano-Meter Film Rheology and Asperity Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is today possible to manufacture so smooth surfaces that they can elastically conform totally to each other over the whole Hertzian contact area. For pure rolling lubrication such surfaces ...
A Semi-Analytical Solution to the Dynamic Tracking of Non-contacting Gas Face Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The gas film stiffness and damping coefficients for a non-contacting gas face seal are obtained from the unsteady nonlinear Reynolds equation using the perturbation method. The seal assembly is ...
Numerical Modeling of Dynamic Sealing Behaviors of Spiral Groove Gas Face Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical model is developed for the dynamic analysis of gas lubricated spiral groove face seals. Effects of the rotor runout, misalignment, face contact, as well as the stiffness and damping ...
25th International Symposium on Ballistics, Beijing, China, 17–21 May 2010
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This issue of the Journal of Applied Mechanics contains 19 scientific papers presented at the 25th International Symposium on Ballistics, 17-21 May 2010, organized at Beijing, China, by the ...
A Novel Model of the Equivalent Viscosity of Simple Viscoelastic Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the Maxwell model in simple shear flow by using the complex analysis, instead of the matrix analysis which is generally used in the literature. It is found that the viscoelastic fluids will behave ...
On the Lubrication of Heavily Loaded Cylindrical Surfaces Considering Surface Deformations and Solidification of the Lubricant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lubrication of a line contact between two cylinders is studied. The viscosity of the oil is assumed to vary with pressure and temperature. The oil is assumed to solidify at a certain pressure, ...
26th International Symposium on Ballistics, Miami, Fl, USA, 12–16 September 2011
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This issue of the Journal of Applied Mechanics contains twenty-three scientific papers presented at the 26th ISB, organized by the National Defense Industrial Association (NDIA, www.ndia.org), ...
Volcanic Eruptions, Large-Scale Modes in the Northern Hemisphere, and the El Niño–Southern Oscillation
Publisher: American Meteorological Society
Abstract: The author analyzes the impact of 13 major stratospheric aerosol producing volcanic eruptions since 1870 on the large-scale variability modes of sea level pressure in the Northern Hemisphere winter. The paper focuses on ...
