Numerical studies on the interactions between a flexible plate and incoming flow

The linear Euler – Bernoullibeam model is employed for the studies on the interactions between a flexible plate and incoming flow. The flow field was simulated by the immersed-boundary method. It is shown that the plate was inhibited at a relative low Reynolds number. When the Reynolds increases, the plate begins to flap and its amplitude increases with the increasing of Reynolds number. The amplitude is small with a large stiffness coefficient. When the mass ratio becomes large, the inertial effect enhances, and the amplitude of the plate is large. With the same material parameters, different initial trailing edge inclination lead to different flapping amplitudes.
