Extracting energy from unsteady flows through vortex control
… for the inflow to the foil. The problem of an oscillating foil placed within a Karman vortex street is investigated with a theoretical model and numerical simulation. The theoretical model is an adaptation of the classical linear theory for unsteady aerofoils. It combines the effects of …

Prediction and analysis of wing flutter at transonic speeds.
This dissertation deals with the instability, known as flutter, of the lifting and control surfaces of aircraft of advanced design at high altitudes and speeds. A simple model is used to represent the aerodynamics for flutter analysis of a two-degree-of-freedom airfoil system. Flutter solutions of …
