First Workshop on Compressible Multiphase Flows
Derivation, closure laws, thermodynamics
23—25 May 2018, Strasbourg, France

Objective of the workshop

In this workshop, we will address the modelling of multiphase flows. The goal is to share modelling methods, difficulties, (rigorous or more phenomenological) analysis, allowing the description of multiphase flows with exchanges (mass transfer, energy exchange…) and apparition of shock waves. A dozen of talks is planned, with several parts dedicated to open discussions. The main subjects will be a priori:

1. The Physics of multiphase flows with mass transfer and high energy exchanges,
2. Derivation and study of PDE models for compressible multiphase flows,
3. Construction of coherent thermodynamical laws.

Note that one-velocity and multi-velocity models will be considered.
