Viscosity and Rheology of In-Service Fluids as They Pertain to Condition Monitoring

Editor(s): A. Rishell

Eleven peer-reviewed papers provide the latest to current research and practices on viscosity and rheology of in-service fluids as they pertain to condition monitoring.

Topics cover:
• Grease Working and Its Role in Consistency Trending
• Possible Impact of In-Service Grease Mixtures with a Stress Rheometer as an Element of a Predictive Maintenance Program
• Comparison of the Effects of Normal Automobile Engine Use on the High Shear Rate Viscosity, Wear, and Volatility of Four Engine Oils
• Die-Extrusion Method for Comparing Changes in Grease Consistency and Flow Characteristics
• Application of Sensors for In-Situ Measurements of In-Service Grease Rheology
• Absolute Viscosity and Sample Density Measurement Methods to Determine and Report Absolute and Kinematic Viscosity Values for Used Lubricating Oils
• Start-Up Viscosity of In-Service Engine Oils at Low Temperatures
• Rheological Property Measurements of Newtonian and Non-Newtonian Fluids with the Falling Needle Viscometer
• Hand-portable Kinematic Viscometer
• Use of Routine Low-Temperature Viscosity Measurement to Prevent Sudden Transformer Failure upon Very Cold Startup
• Low-Temperature Rheological Response of Fresh Versus Used Oils Using the Scanning Brookfield Technique
