论文摘要
我们重新审视具有界面质量的两相多组分流体系统的尖锐接口连续体热力学。由于已发表的工作并不完全一致，因此我们提供了局部平衡方程和熵生产率的严格推导，包括所有相关步骤和数学工具。特别强调的是熵原理的公理形式，同时允许有效的闭合过程。后者建立在熵生产率的适当表示基础上，该速度基于从更精致的模型中获得的结构信息，该模型包括部分动量，并在附录中给出。进一步研究了单方面散装接口物种转移速率获得的闭合关系，这导致了一个新型的模型，该模型在流体界面处的传质模型受吸附表面活性剂的存在影响。我们最终将结果详细比较与有关界面质量的两相多组分流体系统连续热力学的现有文献。
We revisit the sharp-interface continuum thermodynamics of two-phase multicomponent fluid systems with interfacial mass. Since the published work is not fully consistent, we provide a rigorous derivation of the local balance equations and the entropy production rates, including all relevant steps and mathematical tools. Special emphasis is put on an axiomatic form of the entropy principle which, at the same time, allows for an efficient closure process. The latter builds on an appropriate representation of the entropy production rates, which is based on structural information being obtained from a more refined model which includes partial momenta and is given in an appendix. The closure relations obtained for the one-sided bulk-interface species transfer rates are further investigated, which leads to a novel model for mass transfer at fluid interfaces, influenced by the presence of adsorbed surface active agents. We finally compare our results in detail with the existing literature on continuum thermodynamics of two-phase multicomponent fluid systems with interfacial mass.
