Friction Reduction in Lubricated Rough Contacts: Numerical and Experimental Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Combining the contact model of elasticlayered solid with the concept of asperity contact in elastohydrodynamic lubrication (EHL), a mixedlubrication model is presented to predict friction coefficient over rough surfaces ...
Modeling Study of Variable Upwelling Circulation in the East China Sea: Response to a Coastal Promontory
Publisher: American Meteorological Society
Abstract: three-dimensional, high-resolution numerical model is used to investigate processes and dynamics of an intensified upwelling that is induced by a coastal promontory over the East China Sea (ECS) shelf. The center of the ...
Friction of Coated and Uncoated Rough Surfaces in Additive-Free and Fully Formulated Engine Oils Under Boundary and Mixed Lubrication Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Downsizing in spark-ignited engines becomes one of the most effective concepts to achieve fuel economy and emissions requirements and drives operating conditions of major moving engine components into more mixed and boundary ...
A Three-Layer Alternating Spinning Circulation in the South China Sea
Publisher: American Meteorological Society
Abstract: nderstanding of the three-dimensional circulation in the South China Sea (SCS) is crucial for determining the transports of water masses, energy, and biogeochemical substances in the regional and adjacent larger oceans. ...
Topographic Rossby Waves in the Abyssal South China Sea
Publisher: American Meteorological Society
Journal Bearing Surface Topography Design Based on Transient Lubrication Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A transient mixed lubrication model is used to study the performance of a journal bearing subjected to impulse loading, considering mass conservation and the effects of asperities on flow and contact, to explore a novel ...
Erratum: “Profile Design for Misaligned Journal Bearings Subjected to Transient Mixed Lubrication” [ASME J. Tribol., 2019, 141(7), p. 071701; DOI: 10.1115/1.4043506]
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the original publication, Fig. 5 is incorrect. The actual applied loads used for all the simulations can be found in the corrected figure below with a peak vertical load of 13.7 kN in magnitude.
Experimental Study on the Hydrodynamic Performance of a Flexible Connected Double-Module Floating Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A flexibly connected double-module floating structure can be used as the primary component unit of a large multi-module floating structure, revealing some basic principles regarding the interaction of multiple modules and ...
Profile Design for Misaligned Journal Bearings Subjected to Transient Mixed Lubrication
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Misalignment between the shaft and the bearing of a journal bearing set may be inevitable and can negatively impact journal bearing performance metrics in many industrial applications. This work proposes a convex profile ...
Assimilating In Situ and Remote Sensing Observations in a Highly Variable Estuary–Shelf Model
Publisher: American Meteorological Society
