Abstract
The two-dimension problem of sound radiation from the porous circular cylinder saturated by a liquid and rotating around its axis of symmetry is investigated. For the description of the dynamical state of the porous cylinder the Bowen´s theory is used, in accordance of which the porosity is introduced as the inner parameter, satisfying the equation of the evolution type. The numerical example for a case of sandy cylinder, saturated by the kerosene, rotating in air is considered.
