Intended Scientific Scope

Turbulence is a nonlinear phenomenon which is encountered in most fields dealing with the description of the universe and technology, ranging from astrophysics to engineering.
While, for turbulent motion in simple flows, many observations related to the dynamics of turbulence have been reported during the last century, leading to an accurate understanding of interactions between different scales (isotropic turbulence, homogeneous, shear, pure strain, solid body rotation), the knowledge of the nonlinear dynamics of turbulence in complex interactions is still lacunary.

Complex interactions are understood here in the following senses:

(i) interactions between scales and modes in compressible turbulence and (ii) coupling of turbulence with other physical mechanisms such as acoustics, heat and mass transfer, radiation, structure vibrations/deformation, multiphase dynamics...

These advanced research themes have many industrial applications in civil and military aviation, terrestrial transportation, engine design, environmental management and new control devices.

The purpose of the present Conference is to provide researchers from various communities with an updated panorama of knowledge about turbulence and its interactions with other fields.

Main topics

• Fluid Motion/Turbulence Interaction (interacting scales in incompressible turbulence)
• Shock/Turbulence Interaction (interacting scales and modes in compressible turbulence)
• Combustion/Turbulence Interaction (diffusion and/or premixed flame, reactive flows)
• Multiphase flow/Turbulence Interaction (dynamics of Lagrangian-Eulerian and Eulerian-Eulerian regimes, particle, droplet and spray)
• Wave/Turbulence Interaction (acoustics, rotation, stratification, MHD and plasmas)

About 60 presentations, including 10 keynote lectures, will cover these main topics. The keynote papers will be published in a book (Ed. Springer or Cambridge University Press) and other papers will be submitted to a special issue of the Journal "Computer & Fluids".

Further event

The attendants of the Turbulence Conference are invited to participate in the workshop co-organized on June 1st and 2nd by ERCOFTAC SIG4 "Turbulence in Compressible flows" and AFM GST13 "Mécanique des Fluides et Turbulence" (Programme).
