Control of flow separation by vestigial "synthetic jet"
 Tesař, Václav ; Pavelka, Miroslav ; Smyk, E. ; Peszyński, K.
A useful aerodynamic control action may be causing a separation of flow from the wall past which the fluid flows. Several current research activities aim at doing so by oscillating zero-time-mean flow generated in a nozzle located in the wall. The effect is often described as “flow control by synthetic jet”, although it is obvious that the vortex rings generated in the outflow phase of the oscillation are deformed by the controlled flow and also are carried too far away so that they cannot form the classical synthetic jet configuration of vortex rings. Authors describe experiments with such a control applied successfully in an axisymmetric fluidic valve. Presented is a hypothesis explaining the separation mechanism.

No-Moving-Part Two-Regimes Control of an Airfoil Cascade
 Tesař, Václav
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.
