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. Find here the program of the previous workshop.

Several talks are planned, with parts dedicated to open discussions. The main subjects will be a priori:

  • the Physics of multiphase flows with mass transfer and high energy exchanges,
  • derivation and study of PDE models for compressible multiphase flows,
  • construction of coherent thermodynamical laws.

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


The talks will start the afternoon of Monday 21, and finish Tuesday 22. Open discussions will also be possible during the morning of Monday 21. 


Each talk will last 40 minutes and be followed by a session of 20 minutes for open discussions.

A poster session will be organized Monday. If you are interested in presenting your recent works in the topics of the workshop, we would be happy to welcome you. Please contact the organizers, sending a title and an abstract of your poster. For those who would like to submit their contribution without being present, online 15 minute-long talks will be possible too.
