Abstract:

The Maxwell-Stefan is a system of nonlinear equations commonly used in the description of diffusion processes in multi-component systems, like gases with many constituents. I will first discuss how the Maxwell-Stefan system emerges through a process of alignment in the high-friction limit of multi-component Euler flows. Then I focus to:
  1. Analytical issues on existence and uniqueness of the Maxwell-Stefan system and the role of relative entropy.
  2. Structure and existence theory of Maxwell-Steffan Cahn-Hilliard systems.
  3. The connection between minimization of the frictional dissipation and the Maxwell-Stefan system.
