Phenomenology of unsteady separated flow
Abstract
A phenomenological description of the generation of a wake, starting at rest, and a qualitative interpretation are presented. Numerical simulation models which make use of free vortices are then discussed in terms of applications. Experimental observations of the generation of separating wakes downstream of various obstacle forms are described. Results lead to principles of numerical modeling of this type of flow based on a description of wakes as vortex singularities.
