Analytical Prediction of Low-Frequency Fluctuations Inside a One-Dimensional Shock
Saurabh S. Sawant, Deborah A. Levin, Vassilios Theofilis
Linear instability of high-speed boundary layers is routinely examined assuming quiescent edge conditions, without reference to the internal structure of shocks or to instabilities…
A Kinetic Approach to Studying Low-Frequency Molecular Fluctuations in a One-Dimensional Shock
Saurabh S. Sawant, Deborah A. Levin, Vassilios Theofilis
Low-frequency molecular fluctuations in the translational nonequilibrium zone of one-dimensional strong shock waves are characterised for the first time in a kinetic collisional fr…
Laminar separated flows over finite-aspect-ratio swept wings
Kai Zhang, Shelby Hayostek, Michael Amitay +3
We perform direct numerical simulations of laminar separated flows over finite-aspect-ratio swept wings at a chord-base Reynolds number of to reveal a variety of wake st…
On the formation of three-dimensional flows over finite-aspect-ratio wings under tip effects
Kai Zhang, Shelby Hayostek, Michael Amitay +3
We perform DNS of flow over finite-aspect-ratio NACA 0015 wings to characterize the tip effects on the wake dynamics. This study focuses on the development of three-dimensional sep…
Transient growth mechanisms of low Reynolds number flow over a low-pressure turbine blade
AS Sharma, N Abdessemed, SJ Sherwin +1
A direct transient growth analysis for three-dimensional perturbations to flow past a periodic array of T-106/300 low-pressure turbine fan blades is presented. The methodology is b…
