Project: Multiscale modeling of multiphase flows (2025-2028, New-Aquitaine region/UPPA)
Understanding and mastering complex and physically rich flows, such as compressible multiphase flows, which are often unsteady, is of great importance in various fields such as aeronautics, automotive engineering, aerospace, nuclear energy, naval applications, and medicine. Even very simple configurations of flows with resolved interfaces can quickly give rise to flows involving very small inclusions (bubbles, droplets), , leading to inherently multiscale flows. This multiscale nature poses challenges both for modeling and for the simulation of such phenomena. The goal of this project is to contribute to the improvement of models and numerical methods for the simulation of compressible multiphase flows. The central idea of this project is to model subscale phenomena using a stochastic process.
