Description

In previous years, we have presented several results on viscosity measurements using conventional and laser ultrasound techniques [1,2,3]. These results are based on experiments conducted at room temperature. The principle[1], in essence, is to launch ultrasonic shear waves at the interface of a solid and a viscous fluid. The amplitude and phase of the reflected waves were correlated to the viscosity of the fluid.
