摘要：
A comparative study of the performance of different schemes used to solve one-dimensional gas flow equations when applied to the computation of the frequency response of exhaust mufflers is presented. Simple but representative systems with well-known acoustic behaviour were considered. Apart from the classical Lax-Wendroff and MacCormack schemes, the total variation diminishing schemes, flux corrected transport techniques or the innovative space-time conservation element and solution element method were considered. The results provide guidelines for a proper choice of the numerical scheme, taking into account the mesh spacing. (c) 2007 Elsevier Ltd. All rights reserved.
