A primary blast injury occurs as the shock front and the overpressure blast wave move through the body.
In the experiments the dense gas clumps or gas clouds that surround an exploding star were simulated by introducing a plastic grid to disturb the shock front.
The two key pieces of evidence for the jet are a straight line of X-ray emitting gas that points toward Sgr A* and a shock front -- similar to a sonic boom -- seen in radio data, where the jet appears to be striking the gas.
The first baffle off the muzzle is stainless, so as to stand up to the shock front of gases and particles.
It should be noted that the wave, reflected from the shock front of a narrow pulse, is shorter than the wave, reflected from the shock front of a wide pulse, and becomes a shock in a shorter time interval (similar to waves propagating to the right).

The exact position of this shock front changed over time: at times of intense solar activity, Saturn's magnetosphere tended to become compressed and so the shock front moved inwards, but at times when the solar wind was weaker, its magnetosphere tended to expand outwards.
A loading of a structure directly exposed to an incident shock front generated by an above ground explosion takes place during the reflection of this front.

But Howell's group spotted a delinquent la supernova, involving unusual chemicals and a slow shock front.
With the nonlinear Burgers equation and field data, procedures are developed to determine the sampler yield, the duration of inflow, the moving shock front or its velocity, as well as the storage of soil moisture readily available around the sphere of influence of the sink.
