Machine learning has recently become a promising technique in fluid mechanics, especially for active flow control (AFC) applications. A recent work [Rabault et al., J. Fluid Mech. 865, 281–302 (2019)] demonstrated the feasibility and effectiveness of deep reinforcement (DRL) performing AFC over circular cylinder at Re = 100, i.e., laminar regime. As follow-up study, we investigate same problem ...

The aerospace community has long studied active flutter control. Recently, a novel idea, which is energy harvesting from wing vibration under the assumption that certain magnitude of allowed, been attracting attention. balancing problem between piezoelectric and control an research topic. In our previous work, we developed coupled analysis system for piezoelectric–structure–fluid interaction pr...
