建立了工程文献中普遍存在的多组分多相多孔流模型的公理基础。这统一并扩展了文献中出现的各种不同的经验公式。本构约束由热力学第二定律的适当表述导出，相应的耗散不等式建立了解的稳定性。说明了这些模型的凸性和变分结构。
An axiomatic foundation for models of multi-component multiphase porous flow appearing ubiquitously in the engineering literature is developed. This unifies and extends various disparate and empirical formulations appearing in the literature. Constitutive restrictions are derived from an appropriate statement of the second law of thermodynamics, and the corresponding dissipation inequalities establish stability of solutions. The convexity properties and variational structure of these models are elucidated.
