Simulated and actual schlieren images show good agreement at earlier times, but the solid material is too stiff and not sufficiently plastic. The flap springs back after about 300 micro-seconds, which is not in qualitative agreement with the experiment. A detailed comparison of computational and experimental schlieren images can be found on a separate page.
z=0.444m (overall distance 1.964m) | z=0.896m, (overall distance 2.416m) |
The oscillations in the reflection process are no computational error, but occur because the detonation turned fully three-dimensional in the simulation. (Compare Schlieren plot of density on refinement levels, x=0)
