Kinetic Linear Stability Theory for High-Speed Compressible Flows: A High Performance Computing Framework
Irmak Taylan Karpuzcu, Deborah Levin, Vassilis Theofilis
Shock waves in high-speed compressible flows contain finite-thickness, high-gradient regions where the continuum assumption becomes questionable and translational non-equilibrium a…
A Molecular Gas Dynamics Study of Hypersonic Boundary Layer Second Mack Mode Instabilities
Mert Senkardesler, Irmak T. Karpuzcu, Deborah A. Levin +1
A flat-plate laminar boundary layer is simulated at Mach 6 and unit Reynolds number of 1.1e7 using the Direct Simulation Monte Carlo (DSMC) method to capture and analyze spontaneou…
Loss of Axial Symmetry in Hypersonic Flows over Conical Shapes
Irmak T. Karpuzcu, Deborah A. Levin
The assumption of axial symmetry for hypersonic flows over conically shaped geometries is ubiquitous in both experiments and numerical simulations. Yet depending on the free stream…
On linear stability of supersonic flow over a short compression corner at large ramp angles
Irmak T. Karpuzcu, Vassilis Theofilis, Deborah A. Levin
Linear stability of supersonic flow over a short compression corner with ramp angles 30 and 42 is investigated using Direct Simulation Monte Carlo (DSMC) and Linear Stability Theor…
