This study performs global stability/receptivity analyses of hypersonic sweep flows around a blunt body with an infinite span. For the first time, we obtain characteristics leading attachment-line mode to variation angles from 20 70 degrees. The eigenfunctions exhibit instability at edge. At same cross-flow (at small angles) or second Mack larger dominates further downstream. We establish adjoi...

A hybrid artificial boundary condition (HABC) that combines the volume-based acoustic damping layer (ADL) and local face-based characteristic (CBC) is presented to enhance absorption of waves near computational boundaries. This method applied prediction aerodynamic noise from a circular cylinder immersed in uniform compressible viscous flow. Different ADLs are designed assess their effectivenes...
