An Assessment of the State-of-the-Art from the 2019 ARO Dynamic Stall Workshop

Dynamic stall has been a limiting factor in design and operation on rotating systems within the rotorcraft, propulsion, and sustainable energy disciplines for more than forty years, impacting operational performance and component fatigue. In the last decade, significant advances have been accomplished in the understanding, prediction, modeling, and control of dynamic stall on both static and rotating wings. In September 2019, an Army Research Officefunded workshop was held at the Georgia Institute of Technology to evaluate the state of the art and future directions in the understanding and control of dynamic stall. Approximately forty attendees drawn from top experts in the field to graduate students convened to discuss experimental, computational, theoretical, and control research in the field over a two-day period. This workshop was designed to gather the details of these advances and to impart to the broader community the current state of the art in the understanding and prediction of dynamic stall for rotating systems. A summary of the discussions and findings from this workshop are presented here.
