A Systems Approach to Turbulence and Interactions, from Single Phase flow to Two-Phase Flow

Date: 30-31/5/2018

Location: École Centrale de Lyon - Amphi 1,
                36 avenue Guy de Collongue, Écully, France

Organisers: Christos Vassilicos and Claude Cambon

Workshop: SIG35 

This workshop is partly a follow-up of previous ones, in D’Alembert, Paris, in May 2015 and May 2016 and in Marseille, May 2017.

The SIG 35/CHB/ERCOFTAC workshop ‘Multi-point Turbulent Structures and Modelling’ will display advanced modelling and theory, and possibly new experiments.
