Title: Modelled ultrasonic reflection coefficient for a Cannon n10 oil layer on an aluminium plate at 25C. Instituation: The University of Sheffield, UK Date of Generation: 04/08/2022 Keywords: Bearing, meniscus, oil lubrication, grease lubrication Model data This folder containes the modelled reflection coefficients of Cannon n10 calibration oil on an aluminium plate at 25C for 4 different film thicknesses (1um, 20um, 100um, 200um). The R variable is the reflection coefficient across the frequency spectrum for the 4 different thicknesses. The frequency is in MHz, the temperature in celcius. The model data was produced via Equation (2) of the paper "The application of broadband ultrasonic spectroscopy to the study of layered media" Haines et al.
