Turbulent wakes of plates with non-equilibrium similarity scalingsetc15 Tracking Number 75 Presentation: Session: Jets and Wakes 1 Room: Room E Session start: 10:30 Tue 25 Aug 2015 Martin Obligado m.obligado@imperial.ac.uk Affifliation: Imperial College London John Christos Vassilicos j.c.vassilicos@imperial.ac.uk Affifliation: Imperial College London Topics: - Jets and wakes Abstract: We have conducted hot wire anemometry measurements of six different axisymmetric turbulent wakes which demonstrate the existence in all these wakes of non-equilibrium mean flow profile scalings and of the underlying self-preservation and non-equilibrium dissipation scalings. These mean flow profile scalings are different from those of all documented canonical boundary-free turbulent shear flows to date, all of which have been established for very far downstream regions. |
