An Assessment of the Impact of Compressibility on Dynamic Stall
MetadataShow full item record
The effect of compressibility on dynamic stall is assessed, based on a review of past research in this area. A careful discussion of recent research is presented focusing on both model rotor, and 2-D dynamic stall studies where compressibility effects have been quantified. Examples from the various research efforts are discussed, and detailed analysis of the influence of compressibility on the dynamic stall process is presented. Differences between incompressible and compressible dynamic stall physics are identified, and the role of computation in the modeling of the compressible dynamic stall process is discussed.
