Abstract

This work presents the implementation of the ultrasonic shear reflectance method for viscosity measurement of Newtonian liquids using wave mode conversion from longitudinal to shear waves and vice-versa. The method is based on measuring the complex reflection coefficient (magnitude and phase) at a solid-liquid interface. Viscosity measurements were made in the range from 1 to 3.5 MHz at 22.5degC for automotive oil (SAE40) and at 15degC for olive oil. Moreover, measurements of the olive oil were also conducted in the range from 15 to 30degC at 3.5 MHz. The experimental results agree with those provided by a rotational viscometer
