| Vortex structures in finite areas a semicylinder and semisphere are constructed and studied based on exact solutions of the hydrodynamic equations. Influence of dimensionless parameters of the geometry and influence of the Frude numbers on the rarefaction force acting on the semicylinder and semisphere from the stream is determined. It is shown, in particular, that the indicated force is the decreasing function of the dimensionless radiuses and the increasing function of the corresponding Frude numbers. The investigated dependences are important, in particular, for obtaining new abilities of management of force action of flows on streamline bodies. |
