Vortex generator (2) in a flow channel loaded with fluid medium has free surfaces extending in the main flow direction (1). At least two surfaces form side surfaces (3, 4) supported on a channel wall (6). These side surfaces taper toward each other in the flow direction and meet at an acute angle (alpha) at a common edge forming the downstream edge of the vortex generator. At least one surface forms a top surface which lies at an acute angle from the channel wall in the flow direction and forms with the side surfaces flow-off edges. The vortex generator has at least one outlet opening for targeted introduction of a secondary flow (13) into the core flow of the wake (11) produced. An Independent claim is also included for a process for controlling the wake of a vortex generator in a flow channel loaded with fluid medium.
