RISA Mathematical Model for the Mixed Lubrication of Non Conformable Contacts With Asperity Friction, Plastic Deformation, Flash Temperature, and Tribo Chemistry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model is presented in this paper for rollingsliding contacts operating in a mixed regime of elastohydrodynamic lubrication and boundary lubrication. The model is based on the framework of Johnson et al. ...
Response Sensitivity and the Assessment of Nonlinear Vibration Using a Nonlinear Lateral–Torsional Coupling Model of Vehicle Transmission System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The eigensensitivity analysis does not meet the increasing industrial requirements of the dynamic performance of a vehicle transmission system. To reduce vibration, it is necessary to include response sensitivity in the ...
Numerical Solution of the Vertical Structure Equation in the Normal Mode Method
Publisher: American Meteorological Society
Abstract: In a diagnostic study by expanding global data in normal mode functions, Kasahara and Puri found that for zonal wavenumber one, even the seventh vertical mode (the highest mode they presented) contains about 50% of the ...
Retrieval of Water Vapor Profiles from Microwave Radiometric Measurements near 90 and 183 GHz
Publisher: American Meteorological Society
Abstract: Upwelling radiometric measurements at 90 GHz and three side bands near 183 GHz are used to retrieve water vapor profiles over the ocean surface. An algorithm incorporating a new technique of handling moderate cloud cover ...
An Evaluation of the Whitetop Cloud Seeding Experiment through a Covariance Analysis
Publisher: American Meteorological Society
Abstract: The Whitetop experiment concerning cloud seeding was conducted in southern Missouri and northern Arkansas during 1960?64. In general, the early analysis showed the rainfall in the treated areas on days with seeding to be ...
Development of a Two-Dimensional Finite-Element PBL Model and Two Preliminary Model Applications
Publisher: American Meteorological Society
Abstract: We have developed a two-dimensional finite-element model for simulating atmospheric flow in the planetary boundary layer (PBL) of the earth. The finite-element method provides a useful alternative to the conventional ...
Retrieval of Total Precipitable Water Using Radiometric Measurements Near 92 and 183 GHz
Publisher: American Meteorological Society
Abstract: The strong water vapor absorption line at 183 GHz is explored in this paper for retrieval of total precipitable water in the atmosphere. This strong line has generally been utilized in the past for the profiling of the ...
Estimating the Bowen Ratio for Application in Air Quality Models by Integrating a Simplified Analytical Expression with Measurement Data
Publisher: American Meteorological Society
Abstract: n air quality models, daytime sensible and latent heat fluxes are important factors that influence atmospheric stability. These heat fluxes originate from heat that is generated from solar radiation and is then released ...
The Effect of Clouds on Water Vapor Profiling from the Millimeter-Wave Radiometric Measurements
Publisher: American Meteorological Society
Abstract: Simultaneous measurements with the millimeter-wave imaging radiometer (MIR), cloud lidar system (CLS), and the MODIS airborne simulator (MAS) were made aboard the NASA ER-2 aircraft over the western Pacific Ocean on 17?18 ...
