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.

Experiments on Lagrangian Statistics in Intense Turbulence.- Wall-Layer Models for Large-Eddy Simulations of High-Reynolds Number Non-Equilibrium Flows.- Two-Dimensional Turbulence on a Confined Domain with No-Slip Walls.- Turbulence of Drag-Reducing Polymer Solutions.- LES of compressible Inert and Reacting Turbulent Shear Flows.- Turbulent Modification of Upward Bubbly Channel Flow with Surfactant.- Transition and Transition Control in a Square Cavity.- Progress in Large Eddy Simulation Modeling of Temporally and Spatially Complex Land-Atmosphere Interactions.
