Real-time reinforcement learning for turbulent state-dependent control in a bluff-body wake
Junjie Zhang, Chengwei Xia, Xianyang Jiang +2
Controlling turbulent dynamics remains a major challenge because of its chaotic, multi-scale dynamics, which strongly influence the performance of many fluid systems. Here we repor…

Active Flow Control for Bluff Body Drag Reduction Using Reinforcement Learning with Partial Measurements
Chengwei Xia, Junjie Zhang, Eric C. Kerrigan +1
Active flow control for drag reduction with reinforcement learning (RL) is performed in the wake of a 2D square bluff body at laminar regimes with vortex shedding. Controllers para…
