内容記述 | Three-dimensional numerical simulations were conducted using the discontinuous Galerkin (DG) finite-element method to clarify mechanism of bow-shock instability, which has been experimentally observed for a blunt body in a low-gamma gas. Shock-surface formation was computed with a blunt body in Mach 3.9 flow. A well-known numerical instability, the carbuncle phenomenon, often occurs simultaneously in such a flow condition. Sufficient resolution of stream-ward grids is required to obtain a stable solution. Spectral analysis for shock-surface deformation suggests that the observed instability is induced by numerical errors. Moreover, influence of the angles of attack was examined, but bow-shock instability was not observed. Other conditions such as a sharp surface shape and a viscous boundary layer should be examined to obtain a physically unstable flow. | |||||
