| 摘 要： | 换热网络的数值模拟在换热网络的定量分析中起着重要作用。但在模拟计算中,有时表现出数值稳定性差。提高数值稳定性的方法,目前多通过改善算法来实现。本文通过对换热网络数值模拟的误差分析,提出了误差放大因子的概念,并依此选择迭代变量。通过对迭代变量的选择,达到提高换热网络数值模拟稳定性的目的。

| Abstract: | Numerical simulation of Heat Exchanger Networks (HEN) plays an inportant role in the quantitative analysis of HEN. In simulation, however, it has been fore td that numerical stability is not satisfying sometimes. So far the efforts increasing stability are mostly focused on algorithms improved. Through error analysis, this paper presents an idea of error-amplifying factors that can be used to choose suitable iterative variables, which (?)an effectively improve the numeric stability of HEN simulation. |
