The Barus–Roelands–Eyring Viscosity Artifice: A Catastrophe for Elastohydrodynamic Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Ward Winer was a pioneer in the high-pressure rheology of liquid lubricants who championed the use of viscometers to understand the rheology of elastohydrodynamic lubrication (EHL). The classical approach to EHL ...
Application of the Ree-Eyring Model to Liquid Lubricants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. One of the many contributions of Professor Ward Winer to tribology was his insistence that constitutive equations for liquid lubricants have a basis in empirical fact. He was awarded the 1986 Tribology Gold Medal ...
The Pressure-Viscosity Coefficient of a Perfluorinated Polyether Over a Wide Temperature Range
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An unbranched perfluoropolyether is the current ball bearing lubricant for deep space flight. We report measurements of viscosity to moderate pressures for the calculation of pressure-viscosity ...
Friction in Lubricated Concentrated Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Actual Eyring Models for Thixotropy and Shear-Thinning: Experimental Validation and Application to EHD
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Eyring sinh law is presently the most well-accepted model for shear-thinning of EHD lubricants at high pressure. It was, however, not accepted for this purpose by Eyring, who found it to ...
Discussion: “Quantitative Comparisons Between Measured and Solved EHL Dimples in Point Contacts,” (Yang, P., Kaneta, M., and Masuda, S., 2003, ASME J. of Tribology, 125(1), pp. 210–214)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The authors have produced a compelling argument to explain EHL dimple formation as resulting from a temperature-viscosity effect. I believe that their explanation is correct. They have solved ...
A Note on the Use of Roelands Equation to Describe Viscosity for EHD Hertzian Zone Calculations
Publisher: The American Society of Mechanical Engineers (ASME)
Elastohydrodynamic Film Forming With Shear Thinning Liquids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent advances in high pressure rheometry have elucidated the shear response of liquid lubricants at the high shear stress characteristic of the traction generating region of lubricated concentrated ...
A Universal Mixing Rule for the High-Pressure Viscosity of Oil/Refrigerant Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bearing life analysis for the rolling element bearings in refrigeration compressors requires an accurate estimate of the film thickness. An alternative is offered here to the experimentally challenging pressure–viscosity ...
A Scaling Parameter and Function for the Accurate Correlation of Viscosity With Temperature and Pressure Across Eight Orders of Magnitude of Viscosity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Quantitative calculations of film thickness and friction in elastohydrodynamic lubrication will require that the low-shear viscosity, μ, be described with far greater accuracy than it is today. ...
