Optimal Reconstruction of Inviscid Vortices
Ionut Danaila, Bartosz Protas
We address the question of constructing simple inviscid vortex models which optimally approximate realistic flows as solutions of an inverse problem. Assuming the model to be incom…
Wake Effects on Drift in Two-Dimensional Inviscid Incompressible Flows
Sergei Melkoumian, Bartosz Protas
This investigation analyzes the effect of vortex wakes on the Lagrangian displacement of particles induced by the passage of an obstacle in a two-dimensional incompressible and inv…
Computation of Steady Incompressible Flows in Unbounded Domains
Jonathan Gustafsson, Bartosz Protas
In this study we revisit the problem of computing steady Navier-Stokes flows in two-dimensional unbounded domains. Precise quantitative characterization of such flows in the high-R…
Optimal Nonlinear Eddy Viscosity in Galerkin Models of Turbulent Flows
Bartosz Protas, Bernd R. Noack, Jan Östh
We propose a variational approach to identification of an optimal nonlinear eddy viscosity as a subscale turbulence representation for POD models. The ansatz for the eddy viscosity…
