摘要

This paper deals with model predictive control of a separated flow around a 2D circular cylinder at a low Reynolds number. The magnitude of the radial velocity on a small region of the cylinder surface is regarded as the control input. We set the objective function including a viscous dissipation function for each optimization step. In numerical simulations, flow separation and vortex shedding are suppressed. An apparent reduction in a drag coefficient is also observed.
