Abstract

The article is dedicated to the results of experimental studies of the pressure distribution on the surface of plane-circular cylinders, and to the flow visualization. The experiments were conducted in a wind tunnel of open type of rectangular cross-section in the range of Reynolds numbers from 15000 to 50000. The flow visualization on the surface of the studied samples was carried out by means of injection of carbon-kerosene suspension into the flow, and on the basis of numerical simulation. The findings showed that on the surface of plane-circular cylinder one could observe two boundary layer separations - at the coupling sites of curvilinear and plane parts. It was determined that the nature of the flow of the front and the stern parts of the round and plane-circular cylinder is qualitatively similar, at the same time on the plane parts of the plane-circular cylinder there is an increase of the hydrodynamic boundary layer
