Abstract

In this paper we discuss an appropriate choice of a cost functional for vortex reduction for unsteady flows described by the Navier-Stokes equations. We discuss different possibilities for a definition of a vortex and for a corresponding cost functionals. The resulting optimal control problem is analyzed and numerical experiments are provided.
