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稳健面向对象公式

摘要 热流体流的面向对象公式通常会产生大型非线性方程系统，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 。使用这个术语，方程可以变成一种形式，其中所有非线性计算都是显式的。这使得即使是复杂的体系结构也能实现健壮且面向对象的公式化。飞机环境控制系统的建模是作为一个可能的应用示例提出的。
