This volume comprises the communications presented at the ETC 11, the
EUROMECH European Turbulence conference held in 2007 in Porto.
The scientific committee has chosen the contributions out of the
following topics: Acoustics of turbulent flows; Atmospheric turbulence;
Control of turbulent flows; Geophysical and astrophysical turbulence;
Instability and transition; Intermittency and scaling; Large eddy
simulation and related techniques; MHD turbulence; Reacting and
compressible turbulence; Transport and mixing; Turbulence in multiphase
and non-Newtonian flows; Vortex dynamics and structure formation; Wall
bounded flows.
