Feedback control of unstable steady states of flow past a flat plate using reduced-order estimators (2009, methodology): “…from the actuation, in studies using open-loop control by steady or periodic forcing, is often quantified in terms of the momentum coefficient Cμ (Greenblatt & Wygnanski 2000; Taira & Colonius 2009a) which is defined as Cμ = ρU 2actσact 1 2 ρU 2∞c (4.3) where Uact is the constant actuator…”
