Abstract: A numerical simulation of flow in a channel with a right-angled step has been performed on nonstructured meshes having different resolving powers with the use of high-accuracy WENO schemes. The calculated shockwave structure of this flow was compared with analogous structures described in the literature. Accuracy criteria of numerical calculations, associated with the position of shock-wave structures, are discussed. Recommendations on practical use of high-accuracy difference schemes for calculations on nonstructured meshes are given.

Keywords: channel, step, supersonic flow, numerical simulation, WENO scheme.
