Query: Averaged dynamics of two-phase media in a vibration field   The averaged dynamics of various two-phase systems in a high-frequency
vibration field is studied theoretically. The continuum approach is applied to
describe such systems as solid particle suspensions, emulsions, bubbly fluids,
when the volume concentration of the disperse phase is small and gravity is
insignificant. The dynamics of the disperse system is considered by means of
the method of averaging, when the fast pulsation and slow averaged motion can
be treated separately. Two averaged models for both nondeformable and
deformable particles, when the compressibility of the disperse phase becomes
important, are obtained. A criterion when the compressibility of bubbles cannot
be neglected is figured out. For both cases the developed models are applied to
study the averaged dynamics of the disperse media in an infinite plane layer
under the action of transversal vibration.
