Wave propagation in porous medium containing emulsion is numerically investigated. The two-velocity, two-stress mathematical model of porous medium is used. The power law constitutive relation for emulsion is taken. The viscous friction force and associated mass force are accounted in the interaction force between porous medium and emulsion. The pulse evolution in porous medium saturated with emulsion is calculated. The model parameters of the emulsion are taken from experimental investigations of the other authors. The calculation results on wave evolution are compared with that for the porous medium saturated with water and oil. It is shown that there is a frequency range where wave attenuation in porous medium saturated with emulsion is higher than attenuation in water or oil saturated porous medium. The effective viscosity estimates of the emulsion were made and the dispersion curves for linear waves in the porous medium containing emulsion were analyzed.
