Acoustics-based Active Control of Unsteady Flow Dynamics using Reinforcement Learning Driven Synthetic Jets
A DRL agent uses far-field acoustic measurements from a hydrophone array as its sole feedback to drive synthetic jets on a cylinder, achieving up to 9.5% noise reduction and 23.8% drag reduction at Re=100.
