We propose here a new approach to optimally control incompressible viscous flow past a circular cylinder for drag minimization by rotary oscillation. The flow at Re = 15000 is simulated by solving 2D Navier–Stokes equations in stream function-vorticity formulation. High accuracy compact scheme for s...
