Flow body (1) having a flow body surface (2) which forms a flow contour surface (3) around which a fluid is intended to flow, and having at least one flow-influencing apparatus (7) for influencing the flow of the fluid flowing around the flow-surface (2), which in each case has: a passage (10) for connecting the fluid flowing around the flow surface (2) to an actuator area, which is arranged in the flow body (1), of an intake and blowing-out apparatus, a depression (20) which is arranged alongside the passage (10), seen in the flow body depth direction (S-T) and is formed by a depression section (21) of the flow surface (2) on a flow-influencing area within the flow contour area (2a) of the flow surface (2), such that a boundary wall (11) is formed as part of the depression surface, such that, when fluid is periodically and mutually alternately blown in and out through the passage (10), a spin (DR) can be produced by means of the intake and blowing-out apparatus in the flow of the fluid flowing around the flow surface (2), the rotation axis of the spin (DR) is directed along the assumed flow body depth direction (S-T).
