If a torus was traveling supersonically, could its shock fuse diamond?

Question

When something travels supersonically, there is a large pressure wave in its wake. Also, when the peaks of waves interact, they make a bigger peak. So, if a ring traveled supersonically, would the pressure of the shock directly behind the hole in the ring be enough to fuse carbon into diamond?

Answer 1

I'm not sure shockwaves would even work that way for a torus, you might get a calm zone in the middle depending on the size of the hole.

However, it'd be turbulent shock, certainly not precise enough to do anything useful.  And it takes more than just pressure to make diamond, you also need heat, and exclusion of other things that can interfere with the process.
