to simulate airflow around cone-shaped geometries at Mach 16. What they found stunned them: symmetrical expectations gave way to angular instabilities, wavy separation lines, and flow breaks.

Surprising results from hypersonic air flow simulations could help design stronger, faster and more durable supersonic ...

Lihong V. Wang explaining how Mach cones are formed and why photonic Mach cones are difficult to record. This material relates to a paper that appeared in the Jan. 20, 2017, issue of Science ...

These discoveries could transform the design of ultra-fast vehicles. Researchers at the University of Illinois used supercomputers to model flows at Mach 16 around cones. Their simulations revealed ...

At Mach 3.2, with the spike fully aft, the air-stream-capture area has increased by 112 percent and the throat area has shrunk by 54 percent. The cone shape of the spike also incrementally reduces ...

At Mach 16, they observed breaks in the flow within the shock layers, near the cone's tip, where air molecules become more viscous. Interestingly, these breaks were absent at Mach 6, highlighting ...

Filtered Rayleigh Scattering (FRS) has been used to image turbulent structure on flat-plate boundary layers and is now being applied to studies of the transitional boundary layer over elliptic cones ...
