Abstract
Research within the past five years (e.g., References 1 to 5) identified a multitude of mechanisms whereby shock interactions can affect turbulence. These mechanisms include: (1) direct vorticity amplification, (2) production of vorticity from incident sound and entropy modes, (3) bulk compression and (4) shock-induced streamline curvature as “extra rates of strain,” (5) instantaneous shock focusing, and (6) direct effects of shock motion/dynamics/instability. The present paper addresses three facets of this last issue, the effects of shock motion upon turbulence/“unsteady vorticity.”
Research was supported by the National Aeronautics and Space Administration under NASA Contract No. NAS1-17170 while this author was in residence at ICASE, NASA Langley Research Center, Hampton, VA 23665. This work is declared to be a product of U.S. Government research and therefore in the public domain.
