A Compression-Directional Entropic Stress Method for Shock-Regularized Compressible Flow
Bonan Xu, Chihyung Wen, Peixu Guo
We introduce the Compression-Directional Entropic Stress (CoDeS) method inspired by information geometric regularization. CoDeS replaces scalar multidimensional entropic pressure w…

Nonlinear dynamics involving multiple modes in high-speed transitional boundary layer
Xiao-Bai Li, Yifeng Chen, Chihyung Wen +1
Extensive studies have investigated the transition mechanism of boundary layers initiated by a single primary instability. In a real-world scenario, however, multiple primary insta…

Role of acoustic metasurface in the nonlinear mode-mode interaction and breakdown of hypersonic boundary layer
Yifeng Chen, Peixu Guo, Chihyung Wen
Boundary-layer instability and transition control have drawn extensive attention from the hypersonic community. The acoustic metasurface has become a promising passive control meth…
