DSMC Study on Unsteadiness of Supersonic Flow Over a Cylinder

Mert Senkardesler, Irmak T. Karpuzcu, Deborah A. Levin

Unsteady flow over a 30 $\mu$m diameter cylinder at Mach 4 is investigated using Direct Simulation Monte Carlo across Reynolds numbers from 270 to 6750, spanning slip-flow to near-co…
