利用渐近分析方法，建立了管网气体动力学的新模型。该模型由等温欧拉方程推导而来。我们给出了模型的推导和数值结果，说明了模型的有效性和性质。我们将新模型与数学和工程文献中的现有模型进行了比较。我们进一步给出了一个样本网络的数值结果。版权所有©2009 John Wiley & Sons， Ltd
We introduce a new model for gas dynamics in pipe networks by asymptotic analysis. The model is derived from the isothermal Euler equations. We present the derivation of the model as well as numerical results illustrating the validity and its properties. We compare the new model with existing models from the mathematical and engineering literature. We further give numerical results on a sample network. Copyright © 2009 John Wiley & Sons, Ltd.
