Abstract
An analysis is made of perturbations propagated during relaxation through a viscoelastic fluid containing gas bubbles. On the basis of a single-velocity homogeneous model for the medium, with the wavelength λ much larger than the distance δ between bubbles and than the radius R of these bubbles (λ»δ»R), an equation is derived which describes the development of a velocity perturbation in the mixture. The results are then compared with the behavior of a perturbation wave in a Newtonian fluid with gaseous inclusions.
