“…Moreover, the bubble height, defined as the maximum vertical distance between the aerofoil surface and the highest velocity found in the boundary layer, is strongly affected by the change in incidence angle. Figure 9b shows that both bubble height and length decrease with increasing angle, which confirms the observations of Visbal et al (2009), Ol et al (2005, Burgmann and Schröder (2008). Furthermore, a comparison of the results at lower and higher Reynolds numbers by Burgmann and Schröder (2008) shows that for the present work the separation and reattachments locations are found, respectively, more upstream and downstream, whereas the transition point is located in between the lower and higher Reynolds number cases.…”

“…9a-d are all in agreement with the general trends found by Burgmann and Schröder (2008), Pauley et al (1990) and Visbal et al (2009) where the bubble characteristic locations move more upstream as the angle of attack increases. The forward shift of the separation point is a consequence of the increased unfavourable pressure gradient on the aerofoil at higher incidence angles.…”

“…The membrane's benefit already exists for the initial unbounded flow environment at h/c = 2 and can mainly be related to flow induced cambering of the membrane, resulting in lift enhancing pressure modification on the suction-side of the wing, seen in previous rigid cambered wings (Pelletier and Mueller, 2000) and membrane wing studies (Visbal et al, 2009;Rojratsirikul et al, 2010;Shyy et al, 2005;Gordnier and Attar, 2014).…”

“…In this category, McGowan et al [46] and Ol et al [50] have analyzed the forces and flowfields for unsteady motions with LEVs over a broad parameter space using both experimental and computational methods. High-fidelity simulations of moving and flexible airfoils to characterize unsteady phenomena at low Reynolds numbers have been performed by Visbal et al [70]. Garmann and Visbal [25] and Granlund et al [29] have investigated vortex structures on pitching flat plates in detail through computational and experimental methods, respectively.…”
