Device for generating vortices also method for operating the device.

Device for generating and / or destruction of vortices in a flow medium (S), comprising a flow channel (12) and one or more profiles (1) arranged in the flow channel (12) to circulate around the middle flow (S), wherein the or any profile (1) is associated one belonging to the device outer drive and designed to generate a periodic oscillating movement of the respective profile (1) relative to the flow medium (S) with a frequency Circular omega, characterized in that the periodic oscillating movement consists of a pure translational displacement of the profiles (1) perpendicular to a flow direction of the flow medium (S).
