Аннотация: ROTATIVE AND VIBRATIONAL MOTION OF A CYLINDRICAL POROUS BODY IN A VISCOUS LIQUID WITHIN THE BRINKMAN MODEL Abstract. Background. The investigation of the viscous fluids and submerged porous bodies relative motion has a significant interest in connection with variety applicationsin the technological processes and natural phenomena. In the present paper we consider the effect of the rotational-oscillatory motion of a cylindrical porous body in a viscous fluid on this fluid flow. The determination of the friction forces moment acting on the control surface outside the porous cylinder was considered. Materials and methods. For the problem solving the methods of mathematical physics and numerical methods had been used. Taking into account the axial symmetry the problem was solved with cylindrical coordinate system using. Results. The fields of filtration velocities inside the porous cylinder and fluid velocity outside the cylinder were determined. Fluid velocity profiles were constructed. The friction forces moment acting on a control surface outside the porous cylinder was determined. Conclusions. It was shown that the fluid velocity field outside the cylinder and the friction forces moment acting on a control surface in the cases of the porous body and impermeable one differs considerable. Keywords: viscous fluid, cylindrical porous body, rotational-oscillatory motion, Brinkman equation
