Abstract: A one of the specific features of hypersonic flow around the blunted head of an object discovered by the computer simulation of aerodynamics of high-speed flight and called the “carbuncle effect” is studied. The following question is analyzed and discussed: is the carbuncle a specific numerical effect related to the discretization of a continuous problem or is the carbuncle a physical reality that manifests itself during high-speed motion in the Earth's atmosphere at large altitudes.

Keywords: aerodynamics, hypersonic flow, carbuncle effect, computer simulation.
