Abstract: In this paper, we study the 2-D isentropic irrotational pseudo-steady supersonic flow around a convex corner for Noble-Abel gas magnetofluid. First, the properties of principal part of the centered simple wave for Noble-Abel gas magnetofluid are given. Second, by constructing the centered simple wave near convex corner, it is proved that the supersonic incoming flow can turn the convex corner by a centered rarefaction wave or a centered compression wave. Additionally, the critical angles corresponding to the arriving of vacuum and sonic state are obtained respectively.

Key words: Noble-Abel gas, convex corner, centered simple wave
