Analysis of the Nonlinear Stability of Circular Couette Flow.

Abstract

The work under this contract aimed at three major goals: (1) Reveal the origin of the despin moment that may cause severe flight instability of spin-stabilized artillery shells with liquid payloads; (2) Explore the potential of high-order perturbation methods for describing nonlinear properties of single modes and mode interactions in hydrodynamic stability; and (3) Analyze the mechanism of state selection in unstable circular Taylor-Couette flow. Keywords: Flight instability of liquid-filled shells; Stability of Taylor-vortex flow; Perturbation methods; Spectral methods; Flow visualization.
