Linear stability analysis of hypersonic boundary layers computed by a kinetic approach: A semi-infinite flat plate at Mach 4.5 and 9
Angelos Klothakis, Helio Quintanilha, Saurabh S. Sawant +3
Linear stability analysis is performed using a combination of two-dimensional Direct Simulation Monte Carlo (DSMC) method for the computation of the basic state and solution of the…
Kinetic modelling of three-dimensional shock/laminar separation bubble instabilities in hypersonic flows over a double wedge
Saurabh S. Sawant, Vassilios Theofilis, Deborah A. Levin
Linear global instability of the three-dimensional (3-D), spanwise-homogeneous laminar separation bubble (LSB) induced by shock-wave/boundary-layer interaction (SBLI) in a Mach 7 f…
Linear Instability of Shock-Dominated Laminar Hypersonic Separated Flows
Saurabh S. Sawant, Ozgur Tumuklu, Vassilis Theofilis +1
The self-excited spanwise homogeneous perturbations arising in shock-wave/boundary-layer interaction (SWBLI) system formed in a hypersonic flow of molecular nitrogen over a double…
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…
