Abstract:

The UTIAS Implosion Driver uses the wave dynamics of a hemispherical implosion to raise the pressure and temperature of its driver gas to extreme values. Strong planar shock waves are thereby generated which alleviate the current shock-velocity plateau of conventional shock tubes. An analytical and experimental study was made of the performance of a 1-in dia shock tube driven by an 8-in dia hemispherical implosion driver. The analytical performance of the shock tube was predicted by numerically solving the set of governing nonlinear partial differential equations including appropriate loss mechanisms in the different regimes of the flow. A simplified solution was developed in the form of a simple equation allowing the maximum expected shock velocity to be predicted for a given set of initial conditions. Modified author abstract
