GENERAL SCHEME OF VORTICITY DISTRIBUTION IN STREAM WHILE FLOWING AROUND CYLINDER

Abstract. In the present paper the author gives the substantiation of the general scheme of vorticity distribution while flowing around the cylinder in order to take into account its effect on the amplitude of the vertical displacement of current line in stratified stream. To do this, the following configuration is used: stream is divided into two areas, in which vorticity is concentrated. The first zone is a thin boundary layer with velocity distribution at the outer edge; the second zone is a thin laminar wake behind the body. In the rest area of stream fluid is considered ideal.
Key words and phrases: завихренность, стратифицированный поток, число Фруда, вертикальное смещение линии тока, пограничный слой, ламинарный след, силовые источники, vorticity, stratified stream, Froude number, vertical displacement of current line, boundary layer, laminar wake, power sources.
