Abstract
This talk explores delocalized collision models and their role in connecting particle-level dynamics with macroscopic descriptions of dense gases and sprays. We first show that several classical delocalized collision models can be placed within a unified framework that admits conservative formulations, associated conservation laws, and entropy inequalities. We then turn to dense gas–particle mixtures: starting from a particle system, we derive coupled Enskog equations together with their conservation properties and an H-theorem. Finally, we explain how an Eulerian–Lagrangian thick-spray model arises as a hydrodynamic limit of the coupled Boltzmann–Enskog equations, illustrating the transition from kinetic to continuum descriptions.
