Abstract: Airfoil cascades are essential parts of energy converting machines. The paper discusses a new concept of flow control in the cascade, inspired by fluidic amplifiers based on the Coanda effect. In place of mechanically articulated blades, the airfoil properties are controlled by auxiliary flow issuing from a slit nozzle in the blade. The alternate attachment to either one of a pair of attachment walls results in two alternative flow regimes. Several applications are discussed in detail, mainly concentrating on a cascade controlling the entrance flow into the vortex chamber of a turn-down flow control valve.
Keywords: airfoil cascade; fluidic valves; separation control
