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…
