Method for controlling a gas mass flow, flow channel and turbo machine with a flow channel

The invention is a method for controlling a through a flow channel (17) of a turbomachine (1) flowing the gas mass flow (9, 10), in which at least one in the flow channel (17) arranged plasma actuator (7) is activated and characterized (the gas mass flow 9, 10) at least partially accelerated. In addition, a flow passage (17) and a turbomachine (1) with this flow channel (17) are claimed.
