| Abstract: | Two possible regimes of inviscid gas flow in a nozzle with a convex angle-type contour ahead of the throat are described, namely, the regimes with the choking in a cross-section passing through the angle vertex and in the throat, respectively. The conclusions are supported by numerical results obtained using a time-dependent method based on the Godunov-Kolgan finite-difference scheme.Moscow.
