Local algebraic instability of shear-flows in the Rayleigh equation

  • 1. Via Guglielmo Marconi 11, 35123 Padova (Italy)

Description

Because of its non-Hermitian property, the stability analysis of a shear-flow system is rather complex. While the Kelvin-Helmholtz instability, being a spatially global and temporally exponential mode, can be detected by a standard analysis of eigenvalues, there may exist a variety of different instabilities. Invoking time asymptotic analysis, the existence of spatially localized and temporally algebraic instability in non-monotonic shear-flows with multiple stationary points is shown
