Hydrodynamics of swimming in stingrays: numerical simulations and the role of the leading-edge vortex (2016, background): “Lewin & Haj-Hariri (2003) also showed that the foil efficiency reduces when the LEV gets separated.”
Wake topology and hydrodynamic performance of low-aspect-ratio flapping foils (2006, methodology): “…variability in the foil geometry and the flow field (Jones, Dohring & Platzer 1998; Isogai, Shinmoto & Watanabe 1999; Tuncer & Platzer 2000; Wang 2000; Mittal, Uttukar & Udaykumar 2002a; Mittal et al. 2003; Lewin & Haj-Hariri 2003; Pedro, Suleman & Djilali 2003; Guglielmini & Blondeaux 2004).”
A model for the symmetry breaking of the reverse Bénard–von Kármán vortex street produced by a flapping foil (2008, positive): “…foil have been observed in many experimental (Jones, Dohring & Platzer 1998; Buchholz & Smits 2008; von Ellenrieder & Pothos 2008; Godoy-Diana et al. 2008) and numerical studies (Jones et al. 1998; Lewin & Haj-Hariri 2003) even when the geometry of the problem and the flapping motion are symmetric.”
DISSECTING INSECT FLIGHT (2005, result): “Later numerical studies confirmed a similar scaling (Lewin & Haj-Hariri 2003).”
Bifurcating flows of plunging aerofoils at high Strouhal numbers (2012, background): “In viscous simulations, Lewin & Haj-Hariri (2003) observed aperiodic and asymmetric solutions, corresponding to unstable deflected jets for an aerofoil oscillating at StA ≈ 0.48 and at Reynolds number Re = U∞c/v = 500 (where v is the kinematic viscosity).”
Recent progress in flapping wing aerodynamics and aeroelasticity (2010, background): “Lewin and Haj-Hariri [139] conducted 2-D numerical investigations for fluid dynamics associated with elliptic-like plunging airfoils at Re=5.”
Influence of wing kinematics on aerodynamic performance in hovering insect flight (2007, background): “Lewin & Haj-Hariri (2003) performed a similar numerical study for heaving airfoils.”
The Development of a Biologically Inspired Propulsor for Unmanned Underwater Vehicles (2007, result): “This was unexpected since existing data on flapping foils show that the peak thrust is significantly smaller than the lift force [18], [25], [29], [31], [ 32 ].”
On the rules for aquatic locomotion (2017, background): “The shedding of leading-edge vortices may be an important factor [1,6].”
Computational modelling and analysis of the hydrodynamics of a highly deformable fish pectoral fin (2010, background): “Although there are a number of computational studies that have examined both two-dimensional (Tuncer, Walz & Platzer 1998; Ramamurti & Sandberg 2001; Lewin & Haj-Hariri 2003) and three-dimensional rigid flapping foils (Blondeaux et al. 2005; Techet et al. 2005; Dong et al. 2006), the level of…”
