A reduced-order modeling approach for natural gas transient flow in pipelines is proposed. The Euler equations are considered as the governing equations and solved numerically using the implicit Steger–Warming flux vector splitting method (FSM). Next, the linearized form of the equations is derived and the corresponding eigensystem is obtained. Then, a few dominant flow eigenmodes are used to construct an efficient reduced-order model. Two well-known test cases are presented to demonstrate the accuracy and the computational efficiency of the proposed method. The results obtained using the proposed reduced-order model, are in good agreement with those of the direct numerical method. Moreover, it is shown that the proposed reduced-order model is more efficient than the conventional numerical techniques for transient flow analysis of natural gas in pipelines. 1-2 Journal of Petroleum Science & Engineering 73 ARTICULO Bouchonneau, N. 46863 Sauvant-Moynot, V. 43444 Choqueuse, D. 46864 176989 176989 0 0 0 0 244808 BAAB BAAB 2026-03-05 200048924 0 200048924 2026-03-05 18:58:06 2026-03-05 ARTICULO
