Review of rotating wing dynamic stall: Experiments and flow control

Dynamic stall has been a technical challenge and fluid dynamical subject of interest for more than fifty years; but in the last decade significant advances have made understanding, prediction, modeling, control dynamic on rotors. This paper provides summary state art experiments future directions understanding Experimental data sets are discussed, as well direction research stall. Coordinated testing between airfoils rotating blades, close integration computational experimental studies were found to be productive approaches. Advanced analysis methods, including statistical modal representations, artificial intelligence methods led Investigations devices allowed many useful targeted investigations transition separated flow, not yet resulted commercially implemented device.
