Low-Reynolds-number aerodynamic characteristics of airfoils with piezocomposite trailing control surfaces
Kai Zhang, Bharg Shah, Onur Bilgen
Morphing wings comprised of fixed leading sections with piezocomposite trailing control surfaces have emerged as a novel active control technique for unmanned aerial vehicles. Howe…
Laminar vortex dynamics around forward-swept wings
Kai Zhang, Kunihiko Taira
Forward-swept wings offer unique advantages in the aerodynamic performance of air vehicles. However, the low-Reynolds-number characteristics of such wings have not been explored in…
Aerodynamic characterization of low-aspect-ratio swept wings at
Kai Zhang, Kunihiko Taira
We perform unsteady three-dimensional direct numerical simulations to study the aerodynamic characteristics of finite-aspect-ratio swept wings with a NACA 0015 cross-section at a c…
Laminar separated flows over finite-aspect-ratio swept wings
Kai Zhang, Shelby Hayostek, Michael Amitay +3
We perform direct numerical simulations of laminar separated flows over finite-aspect-ratio swept wings at a chord-base Reynolds number of to reveal a variety of wake st…
