Staggered Finite Difference Scheme for Global Stability Analysis of Incompressible Flows

Autor: Xavier Merle, Jean-Christophe Robinet

Publikováno v: 40th Fluid Dynamics Conference and Exhibit.

Stability of flows, and especially global stability, has become a crucial point in fluid mechanics over the past few decades. Not only asymptotic dynamics is of interest in this case, which is a natural issue of stability analyses, but also short tim
