| Highly resolved solutions of the two-dimensional incompressible Navier- Stokes and continuity equations, describing the evolution of vortex systems, have been obtained accurately and efficiently by spectral collocation methods. Such solutions have formed the basic state for subsequent three-dimensional BiGlobal eigenvalue problem (EVP) linear instability analyses, which monitor the modal response of these vortical systems to small-amplitude perturbations, periodic along the homogeneous axial spatial direction, without the need to invoke an assumption of azimuthal spatial homogeneity. A spectral/hp methodology has been adapted to study instability of vortical flows and has been validated on the isolated Batchelor vortex. Subsequently, a stability analysis of an aircraft wake model, composed of two counter-rotating vortices, has been performed by the present spectral/hp element methodology. | |
