Simulation of Interaction between a Flexible Filament and Fluid Flow by Immersed Boundary Method

Simulations of interaction between a flexible filament and fluid flow were undertaken using an immersed boundary method. A hanging filament immersed in fluid flow was simulated for validation. The movement of the flexible filament in oscillating flow was also predicted numerically. Shedding vortices due to the flapping filament were described in this study.
