Abstract

A Navier-Stokes, a potential flow and an interactive Navier-Stokes/potential flow analysis are described for the determination of the flowfield and of the aerodynamic forces generated by a flapping airfoil in low subsonic flow. The numerical solutions predict thrust for a sinusoidally flapping motion with a mean amplitude of 0.10 c and a reduced frequency of k = 1.5. The thrust producing vortical wake profiles are identified. The interactive Navier-Stokes/potential flow solution method yields as accurate a flowfield prediction as the full domain Navier-Stokes solution.
