摘要
A high order accurate finite difference scheme (UCGVC) for solving the Euler equations is described in this paper. The flux vectors in Euler equations are split by using Sieger-Warming’s flux vectors splitting technique[1]. The flux vectors are approxunated by using upwind compact scheme[2]. In order to preyed the nonphysical oscillations in the vicinity of the shock the group velocity control method is used.
