Some mathematical properties of a barotropic multiphase flow model [PDF]

open access: yesESAIM: Proceedings and Surveys, 2020
We study a model for compressible multiphase flows involving N non miscible barotopic phases where N is arbitrary. This model boils down to the barotropic Baer-Nunziato model when N = 2.
