Figure 6
Time evolution (0 to 1000 µs) of the (a) density, (b) temperature, (c) radial velocity component vr, (d) longitudinal velocity component vz and (e) radial pressure component (−σr) at z = 36 mm from the entrance of the gas cell at different radial points at r = 0, 1, 5 and 10 mm from the axis. The longitudinal component of the velocity is much smaller in magnitude than its radial counterpart. Both the temperature and density decay exponentially with time as indicated by the roughly straight lines after the 3 µs mark on the semi-log plots if the shock-wave-related wiggles are ignored. |
