Riccati-Based Feedback Stabilized Navier-Stokes Flow

Closed-loop simulation of Navier-Stokes flow within "von Kármán vortex street". The vertical component of the velocity field is illustrated. The top video shows the velocity field without any feedback. The middle video shows the influence of the initial feedback, compute via a Bernoulli equation. The bottom video shows the stabilizing influence of the Riccati-based feedback for $\lambda=2$.
