This poster will present a classification of the typical motions of 1-D flexible bodies (“beams”) undergoing arbitrary motions in high-Reynolds-number fluid flows. Previous works have generally focused on rigid bodies and small-amplitude motions. We have developed an implicit numerical scheme coupling the motion of a flexible fiber to ambient vorticity shed from the fiber edges and advected with the fluid flow. The scheme is computationally inexpensive and can compute flows past a variety of active and passive flexible bodies to model flapping flags, swimming fish, falling sheets, and myriad other phenomena of recent interest to theoretical mechanicians.
