| Abstract: | Numerical modeling of supersonic flow over a body with an annular step formed by two coaxial cylinders is performed by the
Godunov method within the framework of the model of an ideal gas. Regimes of nonsteady streamline flow and peculiarities of
the flow associated with the presence of a cylindrical recess in the nose part of the body are analyzed. The influence of
the intensity of injection of an annular wall jet from the bottom of the recess on flow stabilization and the body drag is
investigated. The domain of the existence of steady streamline flow is established.
