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

Date

du mercredi 30 mai au vendredi 1er juin 2018

Location

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

Organisers

• Christos Vassilicos
• Claude Cambon

Motivation

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. Program
