Leading Edge Blowing to Mimic and Enhance the Serration Effects for Aerofoil
Applied Sciences, 2021 Leading edge serration is now a well-established and effective passive control device for the reduction of turbulence–leading edge interaction noise, and for the suppression of boundary layer separation at high angle of attack.

On the aeroacoustic characterization of a robust trailing-edge serration [PDF]
, 2021 This paper presents an experimental study on the aeroacoustics of a flat plate rig with a highly instrumented serrated trailing-edge. The role of near-field flow properties, namely, surface pressure fluctuations and spanwise coherence, in the noise ...

The genus Syrrhoe (Crustacea, Amphipoda, Synopiidae) from the North Atlantic [PDF]
Evolutionary Systematics, 2019 Three species of the amphipod genus Syrrhoe are described from the North Atlantic. The differences between these species are primarily the patterns of serration of the posterior margins of pleonite 3 and urosomite 1 and 2: Syrrhoe affinis has a wide ...
