Excitation of non-modal perturbations in hypersonic boundary layers by free stream forcing. Part II: asymptotic theory and key mechanisms
Ming Dong, Mingze Sun, Qinyang Song +1
Recently, Zhao & Dong (J. Fluid Mech. 2025, vol. 1013: A44) developed a high-efficiency, high-accuracy numerical framework, the shock-fitting harmonic linearised Navier-Stokes (SF-…
On the classical solution for the steady triple-deck equations
Ming Dong, Chao Wang, Qin Wu +1
This paper establishes the existence and uniqueness of classical solutions to the steady Triple-Deck equations, which describe incompressible boundary layer flow over localized rou…
Prediction of bypass transition in hypersonic blunt-plate boundary layers subject to noisy conditions
Qinyang Song, Ming Dong, Lei Zhao
In hypersonic boundary-layer flows over blunt bodies, laminar-turbulent transition exhibits two distinct regimes: for small nose radii, increased bluntness delays transition; beyon…
Asymptotic-analysis-inspired boundary conditions aiming at eliminating polymer diffusive instability
Ming Dong, Dongdong Wan
The recent discovery of polymer diffusive instability (PDI) by Beneitez et al. (Phys. Rev. Fluids, 2023, 8: L101901) poses challenges in implementing artificial conformation diffus…
Excitation of non-modal perturbations in hypersonic boundary layers by freestream forcing: shock-fitting harmonic linearised Navier-Stokes approach
Lei Zhao, Ming Dong
In this paper, we study the receptivity of non-modal perturbations in hypersonic boundary layers over a blunt wedge subject to freestream vortical, entropy and acoustic perturbatio…
