Deriving Indicial Response From Navier-Stokes Equations

Abstract

Report discusses research directed toward recasting indicial-response approach into form appropriate to study of vortex-induced oscillations and related aerodynamic and aeroelastic phenomena. Serves two purposes: to show how deficiencies of prior mathematical model overcome to include effects of memory necessary for modeling of oscillatory but otherwise equilibrium state; and using method developed to analyze particular case of flow past cylinder in periodic forced transverse motion.
