Analysis on linear stability of oblique shock waves in steady supersonic flow

[摘要] An attached oblique shock wave is generated when a sharp solid projectile flies supersonically in the air. We study the linear stability of oblique shock waves in steady supersonic flow under three dimensional perturbation in the incoming flow. Euler system of equations for isentropic gas model is used. The linear stability is established for shock front with supersonic downstream flow, in addition to the usual entropy condition. (C) 2004 Elsevier Inc. All rights reserved.
