Windsurf-mimetic study about unsteady propulsion
Gauthier Bertrand, Ramiro Godoy-Diana, Benjamin Thiria +1
We study experimentally a a three-dimensional reduced model of a sail shape performing pitching oscillations around a mean incidence angle () with respect to an incoming fl…
Waviness and self-sustained turbulence in plane Couette-Poiseuille flow
Manuel Etchevest, Pablo Dmitruk, Supriya Karmakar +3
Direct numerical simulations of a Couette Poiseuille flow were performed near the transition to turbulence to investigate the nonlinear relationship between streak waviness and rol…
On the rheoscopic measurement of turbulent decay in wall-bounded flows
Tao Liu, Victoria Nicolazo-Crach, Ramiro Godoy-Diana +2
Quench experiments where the flow passes from a fully turbulent state to a laminar state by an abrupt decrease in the flow Reynolds number () have been extensively studied in t…
Propulsive performance of a windsurf-inspired pitching foil
Gauthier Bertrand, Tristan Aurégan, Benjamin Thiria +2
We study experimentally a symmetrical rigid foil performing pitching oscillations around a mean incidence angle () with respect to an incoming flow in a hydrodynamic channe…
Aerodynamic consequences of wing damage in dragonflies
Peng Yu, Ramiro Godoy-Diana, Benjamin Thiria +2
Flapping wings are the primary means by which dragonflies generate forces, but they are susceptible to damage due to their inherent fragility. The damage results in a reduction in…
