Engineering Physics Annotation << Back ON SCREENED ROTATION OF A CYLINDRICAL BODY IN IDEAL LIQUID Gerasimov S.A. The potential method in continuous matter physics is an appropriate way to solve problems of hydrodynamics in the case when the boundary conditions for the velocity potential are invariant with respect to turn. The only way to study of the incompressible ideal flow of a liquid around a cylinder rotating inside the part of a cylindrical screen is the numerical solution of the equation of continuity for the vortexoff (irrotational) flow. It is shown that such a partly screened rotating cylinder must produce intensive flows of a liquid with large magnitudes of velocity at large distances from the cylinder. The method of the numerical solution is tested describing the Magnus effect, for which the solution may be obtained by Fourier-series expansion. This means that the rotating screened cylinder must produce the essential lift force even though the medium does not move relative the cylinder. Key words: rotating cylinder, irrotational flow, Magnus effect. Contacts: E-mail: gsim1953@mail.ru Pp. 50-54.
