A new approach to ultrasonic characterization of fluid embedded in two viscoelastic layers using the transfer matrix method

Abstract

In the present work, our objective is to characterize fluids by the ultrasonic pulse echo method. Nowadays, the characterization of these fluids has received a great scientific and practical importance, it requires the development of a more efficient control technique in order to meet the desired quality and safety rules. Indeed, a matrix transfer approach has been introduced to model the signal propagation in a multilayer medium immersed in a fluid. This approach is mainly based on the calculation of the scattered signal in the time domain of a multilayer immersed in water in order to verify the ability to calculate the ultrasonic parameters, and possibly the velocity and attenuation. We then deduce the acoustic properties of fluids and compare with literature data (experimental). This approach has also been suggested as a new alternative to exploit for fluid characterization.
