A method of preventing separation of a fluid flow flowing over a flow surface is described. The method includes generating longitudinal vortices for suppressing or delaying separation of the flow, and enhancing the longitudinal vortices. A flow body system having a flow body and a flow control arrangement is further described.

Method of preventing separation of a fluid flow and flow body system

A fluidic oscillator device, in particular for a or in a flow control system for an aircraft or spacecraft, has a first and a second fluidic actuator, wherein each of the actuators has an inlet for supplying pressure and a first and a second outlet, from which an actuator flow can be discharged. The device further has a fluidic control for controlling an oscillating discharge of the actuator flow from the first and second outlet of the actuators, wherein the control has a connection portion which is arranged between the first actuator and the second actuator.
