Abstract

In this paper we describe 1st and 2nd order finite volume schemes for the solution of the steady Euler equations for inviscid flow. The solution for the first order scheme can be efficiently computed by a FAS multigrid procedure. Second order accurate approximations are obtained by linear interpolation in the flux- or the state space. The corresponding discrete system is solved (up to truncation error) by defect correction iteration. An initial estimate for the 2nd order solution is computed by Richardson extrapolation. Examples of computed approximations are given, with emphasis on the effect for the different possible discontinuities in the solution.
