Abstract

We consider the problem of finding optimal shapes of fluid domains. The fluid obeys the Navier{Stokes equations. Inside a holdall container we use a phase field approach using diffuse interfaces to describe the domain of free flow. We formulate a corresponding optimization problem where flow outside the fluid domain is penalized. The resulting formulation of the shape optimization problem is ...
