Geometrical characterization of stall cells on rectangular wings - Marinos Manolesos (Wind Energy, 2014)
This paper is the first of the outcomes from the GZF032 / 2009–2010 Onassis PhD scholarship grant. It sets the ground for Stall Cell research and based on its findings a number of publications followed (including https://doi.org/10.1063/1.4869726, https://doi.org/10.1016/j.jweia.2015.03.020, https://doi.org/10.1002/we.1609). The main finding, which was not known at the time, is that it is possible to stabilize the inherently unsteady Stall Cells, which are 3D coherent structures of separated flow. The work is relevant to different types of separated flows from Unmanned Air Vehicles to Wind Turbine blades, as Stall Cell instability is linked to flutter and aeroelastic loads.
