Modern approaches to hydrodynamic instability have known an active development in recent years. For instance, multi-dimensional eigenmodes, non-normal optimal perturbation growth, or pseudo-spectra are now routinely computed for increasingly complex flow configurations.
The meeting provides a forum for a systematic and critical presentation of the various conceptual tools that are currently available or being actively explored. Emphasis is placed on a discussion of the premises and the physical settings that these approaches pertain to. Furthermore, the potential of classical local analysis tools for current research is highlighted.
All methodology should be presented in the context of a concrete open shear flow configuration. Session topics include:
-free shear layers
-jets and wakes
-boundary layers
-complex flows (including biological and industrial applications)
-environmental and geophysical flows
