NUMERICAL ANALYSIS OF THE INFLUENCE OF THE SHAPE OF THE VORTEX CELLS BUILT INTO A CIRCULAR CYLINDER ON A STEADY TURBULENT FLOW AROUND ITP. A. Baranov, S. A. Isaev, N. A. Kudryavtsev, Yu. S. Prigorodov, and A. G. Sudakov UDC 532:517.4 On the basis of numerical modeling of a steady two-dimensional turbulent flow around a circular cylinder with built-in vortex cells having smoothed edges, in the near wake behind which a separating plate is positioned, we have analyzed the efficiency of the active method of control of the flow by means of distributed suction from the surface of the central bodies located in the cells Academy of Civil Aviation, 38 Pilotov Str., St. Petersburg, 196210, Russia; email: isaev@SI3612.spb.edu.
