Ultrasonic studies of suspension of glass particles in gel

Main purpose of this paper is the experimental investigation of propagation of ultrasonic waves in suspensions of solid particles (glass beads) in gel. The dependence of phase velocity and attenuation coefficient on the volume fraction and size of solid particles was studied. Special attention has been focussed on determination of the role of size and volume fraction of solid particles on scattering of the waves at ultrasonic frequencies.
