Abstract

ABSTRACT Object-oriented formulation of thermal fluid streams often yields large non-linear equation systems whose numerical solution is difficult to achieve. This paper revisits the fundamental equations for thermal fluid streams and introduces a new term: the steady mass flow pressure . Using this term, the equations can be brought into a form where all non-linear computations are explicit. This enables a robust and object-oriented formulation of even complex architectures. The modelling of aircraft environmental control systems is presented as one possible application example.

定向热流体流网络的鲁棒面向对象公式

热流体流的面向对象公式通常会产生大型非线性方程组，其数值解很难实现。本文重新审视了热流体流的基本方程，并引入了一个新术语：稳定质量流压力。使用这个项，方程可以形成所有非线性计算都是显式的形式。这使得即使是复杂的体系结构也能够实现健壮的、面向对象的公式化。飞机环境控制系统的建模是一个可能的应用实例。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
