| Abstract. | Problem statement. It is required to determine the force acting on a circular cylinder when it moves in a plane-parallel flow containing a rectilinear vortex filament near the cylinder. Results. The possibility of determining the force and torque is shown, acting on the cylinder as vertical points and integrating the pressure at the control points. For comparative analysis, the force was also determined by the classical method, when the impenetrability of the contour is provided by the introduction of an inversion vortex. Conclusions. Periodic changes in forces and moments cause the formation of microcracks in cylindrical structures. Therefore, they are the initial data in the calculation of structural elements for fatigue. |
