In this thesis several incompressible oscillatory flow and
flutter problems were investigated. First, a previously
developed unsteady panel code was modified so that systematic
comparisons with Theodorsen's classical theory could be
accomplished. It was found that the panel code is in excellent
agreement with the Theodorsen results. Second, the panel code
was applied to the analysis of bending- torsion flutter. Again,
general agreement with Theodorsen's flutter predictions was
obtained. In the experimental part of the thesis two flow
visualization experiments were performed. First, the vortical
flow patterns generated by an airfoil executing harmonic
plunge oscillations were visualized. In the second experiment, the interference effects between a stationary airfoil and a
small vane executing plunge oscillations were explored.
