A systems approach to turbulence and interactions: towards high Reynolds number

15-16 May 2017, Marseille


This workshop is partly a follow-up of previous ones, in D'Alembert, Paris, in May 2015 and May 2016.

Transport of passive scalar by an isotropic velocity eld has been extensively studied. What happens when the velocity flow is rendered anisotropic by various effects, as mean shear and mean strati fication, is not well known; triadic closures, with quantitative comparisons to high resolution DNS's, are well suited for a systems approach to such anisotropic turbulence. In addition, it is informative to compare the passive scalar and the active one, such as the density, temperature or concentration fluctuation with a feedback to fluctuating velocity via buoyancy effects.
Of course, a broader range of models, theories, applications, DNS, LES and physical experiments will be addressed as follows:

  • Extension of spectral theory towards anisotropic shear flows, with passive and active (buoyant here) scalar eld. Application to practical (simpler) models for engineering and environment,
  • Towards unsteady and inhomogeneous flows. Contribution to a mean flow theory. Wallbounded turbulent flows.
  • And beyond: improved LES models, flows with solid particles.

The workshop will take place at Ecole Centrale de Marseille, M2P2, domaine universitaire de Château Gombert, Marseille.

It is co-organised by Pierre Sagaut (M2P2) and Claude Cambon (MFAE/LMFA).
