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 Kinetic Study of the Interactions of an Acoustic Vibrating Surface with Hypersonic Boundary-Layer Instabilities
Mert Senkardesler, Irmak T. Karpuzcu, Deborah A. Levin +1
The response of Mack mode instabilities to a simple acoustic vibrating surface (AVS) is studied using the Direct Simulation Monte Carlo (DSMC) method to capture and analyze spontan…

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…
