This paper presents a resonant technique to accurately measure phase-velocity and attenuation of longitudinal acoustic waves in suspensions of solid particles in water. The technique is based on exciting thickness resonances of a layer of fluid and a

A new ultrasonic resonant technique for liquid characterization in the low frequency range is presented. It is based on a waveguide theoretical model describing the acoustic propagation through the liquid and the tube walls. The small liquid samples

Finite-amplitude standing waves in an air-filled tube are studied numerically and experimentally. The standing wave is excited at one end of the rigid-walled tube and a rigid cap is assumed at the other end. The one-dimensional nonlinear second order

A finite element method (FEM) is presented for the study of nonlinear acoustic standing waves inside a chamber. The method is developed using the Galerkin–Bubnov weighted residual formulation and applied to solve the Lagrangian second-order wave eq

Acoustical methods are a very important tool for the characterization of porous materials. In some cases, the appearance of two different longitudinal modes was reported which provides important information of the material properties. It was shown re

Removing very fine particles in the 0.01–1 μm range generated in diesel combustion is important for air pollution abatement because of the impact such particles have on the environment. By forming larger particles, acoustic agglomeration of submic

This paper deals with the study of the velocity and the attenuation of an acoustic wave propagating inside a cylindrical elastic tube filled with a viscous liquid. A theory describing the propagation of the axisymmetrical modes in such waveguides is
