title = "On the Unsteadiness of a Hypersonic Flow over a Double Cone using Kinetic Methods",
abstract = "Direct Simulation Monte Carlo was used to simulate three-dimensional (3D) hypersonic nitrogen cold flow over a double cone at zero angle of attack and results are compared with those of the corresponding axisymmetric (2D) simulation at the same conditions. It is found that the well-known strong shock pattern and closed recirculation bubble seen in 2D flow is absent in the 3D simulations. Instead, axial symmetry is broken in the 3D results, in particular in the conical and bow shocks, as well as in the shear layers. Periodic structures are formed in these flow regions, the origin and characteristics of which are presently being examined using linear global flow instability methods.",
