| Description: | For active flow control, flow around a 2D cylinder is considered a generic example. The von kármán vortices are generated for flow around the 2D cylinder. These vortices impose periodic drag and lift on the cylinder. The objective of this study is to reduce drag, fluctuation of and drag, and lift in order to stabilize the cylinder. Hence, open-loop control and closed-loop control strategies are implemented to control drag and lift. The optimal open-loop control strategy is achieved by parameter study. The optimal closed-loop control strategy is achieved by deep reinforcement learning using the PPO algorithm. |
