In this article, we investigated the shock phenomenon in gas pipeline systems. We particularly address the numerical discrepancies introduced when using a primitive variable-based formulation of the compressible gas flow model. For the analysis, we compared two different schemes, namely, van Leer's second-order Monotonic Upstream-centered Scheme for Conservation Laws scheme (TVD-MUSCL) together with Roe's superbee slope limiter and the fifth-order accurate finite volume weighted essentiallydoi:10.17512/jamcm.2019.4.10 fatcat:v2nbb5duprffxe47fs6qn66wpq
