Abstract
An expression is obtained for the angular velocity of a spherical dispersed particle in a viscous fluid in an external vortex field with an harmonic time dependence. This expression is then used for investigating a system of two rotating dispersed particles whose rotation is the result of the interaction of the particles in the field of an incident sound wave. It is found that such a system possesses a rather interesting nontrivial property: under certain conditions it has a resonant frequency at which the rotation of the particles relative to the fluid is most intense.
