The present disclosure relates to a flow control system, comprising a controller, an ignition device whose activation is controlled by the controller, a combustion-driven jet actuator, and a fuel source in fluid communication with the jet actuator that supplies fuel to the jet actuator. Typically, the jet actuator comprises a combustion chamber, an orifice that serves as an outlet for combustion products emitted from the combustion chamber, and at least one inlet through which fuel is supplied to the chamber for combustion. In use, the combustion-based jet actuator can emit jets of fluid at predetermined frequencies.
