We present a method for computing fluid–structure interaction problems multi-body systems. The fluid flow equations are solved using fractional-step with the immersed boundary proposed by Uhlmann (2005). of rigid bodies recursive algorithms Felis (2017). two systems weakly coupled, so that resulting is cost-effective. accuracy demonstrated comparison two- and three-dimensional cases from litera...

The vortex dynamics of leading-edge vortices on plunging high-aspect-ratio ( AR = 10) wings and airfoils were investigated by means volumetric velocity measurements, numerical simulations stability analysis to understand the deformation filament spanwise instabilities. filaments both wing airfoil exhibit waves, but with different origins. presence a wing-tip causes leg remain attached upper sur...

We present experiments and simulations of plunging maneuvers large amplitude, for velocity ratios 2, defined as the ratio between peak plunge freestream velocity. explore effect airfoil shape by considering a NACA 0012 wing flat plate. The are performed with wings aspect 4 4.86, whereas using model an infinite-aspect-ratio wing. report time evolution force coefficients flow visualizations. A go...
