Wake Mixing in Axial Flow Compressors [PDF]
Volume 1: Turbomachinery, 1996 Over the years it has been speculated that the performance of multi-stage axial flow compressors is enhanced by the passage of a wake through a blade row prior to being mixed-out by viscous diffusion. The link between wake mixing and performance depends on the ability to recover the total pressure deficit of a wake by a reversible flow process.
