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…

Linear stability and spectral modal decomposition of three-dimensional turbulent wake flow of a generic high-speed train
Xiao-Bai Li, Simon Demange, Guang Chen +4
This work investigates the spatio-temporal evolution of coherentstructures in the wake of a high-speed train. SPOD is used to extract energy spectra and empirical modes for both sy…
