Shockwaves in space
Web1 Jan 1976 · The shock wave system about an SST or space capsule model can be simulated in a supersonic or hypersonic (Mach number greater than five) wind tunnel (Fig. 11) by blowing supersonic air over it. The air behind the shock wave is a subsonic radiating plasma at a Mach number less than one. Web11 Apr 2024 · SANTA CLARA, Calif., April 11, 2024 (GLOBE NEWSWIRE) -- Shockwave Medical, Inc.

WebAs with the above example, shockwaves do not propagate through the vacuum of space. This is handwaved by Commander Valtaine referring to it as a "sub-space shockwave," though it isn't made entirely clear. In Star … WebWould a nuke have a shockwave in space? No. A shockwave requires matter to transfer the mechanical wave from place to place. Space is a vacuum. Yes, there are stray particles in it - but the distance between them is far enough that no mechanical shockwave will pass.
Shock waves are common in astrophysical environments. Because of the low ambient density, most astronomical shocks are collisionless. This means that the shocks are not formed by two-body Coulomb collisions, since the mean free path for these collisions is too large, often exceeding the size of the system. Such shocks were first theorised by Frederic de Hoffmann a…
WebThis assumes that the explosive is shaped in a sphere, for example a large sheet would produce a plane wave. Yes, and we even observe them.
