Mack modes in supersonic boundary layer

Year: 2025

Type: article

Abstract: Understanding the transition mechanism of boundary layer flows is of great significance in physics and engineering, especially due to the current development of supersonic and hypersonic aircraft. In this paper, we construct multiple unstable acoustic modes so‐called, Mack modes , which play a crucial role during the early stage of transition in the supersonic boundary layer. To this end, we develop an inner‐outer gluing iteration to solve a hyperbolic‐elliptic mixed type and singular system.
