Аннотация:Abstract—Viscous fluid flows induced by rotational oscillations of a submerged porous spherical shellare determined. The analytical solutions of the time-dependent Brinkman equation inside the porousshell and the Navier–Stokes equation outside the shell are obtained in the Stokes approximation. Themoment of the friction forces exerted on the control surface around the porous body is determined.The solutions obtained are analyzed. Various particular cases including the case of uniform shell rotationare considered.Keywords: porous spherical shell, rotational–oscillatory motion, Brinkman equationDOI: 10.1134/S001546282006004X
