摘要

研究了包含N个非混相正压相的可压缩多相流模型，其中N为任意。当N = 2时，该模型可归结为Baer-Nunziato正压模型。证明了自然数学熵的弱双曲性、非严格凸性和对称形式的存在性。

Some mathematical properties of a barotropic multiphase flow model

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. We prove the weak hyperbolicity property, the non-strict convexity of the natural mathematical entropy, and the existence of a symmetric form.
