Numerical investigation of the development of three-dimensional wavepackets in a sharp cone boundary layer at Mach 6

Direct numerical simulations were performed to investigate wavepackets in a sharp cone boundary layer at Mach 6. In order to understand the natural transition process in hypersonic cone boundary layers, the flow was forced by a short-duration (localized) pulse. The pulse disturbance developed into a...
