Technion Unsteady Wind Tunnel
Unsteady wind tunnel testing of NRELs stall-regulated, 21% thick, S809 wind turbine blade. The airfoil is mounted between two Plexiglas disks and pitched dynamically into the post-stall regime. Synchronously, the freestream is surged dynamically via downstream louver vanes. Surface pressures are scanned at high-speed and integrated to calculate the loads.

Pulsed Coandă Effect Reciprocating Wind Energy Generator (CoRe)
Pulsed Coandă effect reciprocating wind energy technology demonstrator tested in an open-jet wind tunnel. One degree-of-freedom circular cylinder mounted on a pivot is counterbalanced by tension springs and loaded with a calibrated electromagnetic brake. Two diametrically disposed spanwise blowing slots are pulsed alternately to produce bi-directional transverse loads (lift) made possible by the Coandă-Effect.
