Abstract
The analysis and prediction of fluid-structure interaction for viscous, separated flows presents a great challenge to the aeroelastician. In this paper a zonal method for the computation of unsteady, viscous, separated flows over airfoils is presented. The flowfield is divided into a viscous inner zone, where higher grid resolution may be used, and an inviscid outer zone. Zonal grid solutions are presented for subsonic and transonic flows over a NACA-0012 airfoil subject to ramp and oscillatory motions. Transonic shock/boundary layer interaction and dynamic stall effects are encountered during the unsteady motion. The computed solutions are in good agreement with available experimental data.
