| Abstract: |
| Numerical simulation has been conducted on the propagation of the explosion wave on the primary-secondary basis in an axisymmetric tube with varying cross section, using the MUSCL with second-order precision, the non-structural, self-adaptable mesh technique, and the finite volume form. The results show that the shock wave flow field is uniform and steady with good waveform when the explosion wave on the primary-secondary basis runs into the target region. Desired overpressure and duration of the shock wave could be obtained if the explosive energy of the driver section is properly increased. |
