ECOGEN is a CFD plateform written in C++ object oriented programming langage. It is dedicated to numerical simulation of compressible multiphase flows. It has the vocation to share academics researches in the multiphase flow field in direction to ohter academics but also for industrials, students, etc.

What is a diffuse interface? In DIM theory, the interfaces between pure phases are captured as diffuse numerical zones meaning that one goes continuously from one phase to another.

1D extraction of the diffuse interface zone of a water droplet.

This way is possible thanks to a thermodynamical consistency. Then, the flow solution does no longer requires interface tracking algorithms: It became easy to simulate complex topological shape evolutions between miscible or non miscible fluid. Moreover, pressure waves (shock waves, acoustic waves) can propagate and interact properly in the whole flow.

The basic research on DIM is now matured enough to propose ECOGEN, a numerical tool that can be largely cast and use to solve industrial as well as research multiphase flow problems.
