Extended Model for Pressure Wave Fluid Characterization Setup including Diffraction Effects

Description

Physical fluid parameters like, e.g. mass density, sound velocity and viscosity can be determined by utilizing ultrasonic sensors. In this contribution we investigate the utilization of a sensor setup, previously developed and validated for determining the characteristic acoustic impedance of fluids, to determine the longitudinal viscosity of (particularly low-viscous) liquids. Besides the basic sensor setup an according 1D-model and a comparison of simulation results to measurement results obtained with a test device are presented.
