Abstract: A passive method for reducing the drag of cylinder by installing a flat plate behind it at a Reynolds number $\mathrm{Re}=10^5$ has been studied. The paper presents the results of an ANSYS Fluent simulation of the flow around the cylinder-plate system, including the velocity and pressure fields, streamlines, and the dependences of the drag coefficient and the position of the separation point on the surface of the cylinder on the relative length of the plate. It has been found that the drag coefficient of the cylinder-plate system can be reduced by approximately $40\%$ compared to the case of an isolated cylinder.
Keywords: cylinder-plate system, drag coefficient, separation point.
