“…It can be found from the test results that the overpressure contours (at a fixed pressure) on the ground look like an ellipse, with weaker shock waves along the x ‐axis and stronger shock waves along the y ‐axis, as shown in Figure a. Based on previous studies , the overpressure in the jet direction is the maximum. Thereby the resultant overpressure contours on a sliced plane at x = 0 can be drawn as Figure b.…”

Large-scale experimental investigations were conducted on the flow structures and intensity of shock waves generated by the rupture of a high-pressure pipeline. In the experiments, the bursting of pipes was caused by an initial crack introduced on the upper center of the pipe. The crack velocity, pressure-time trace and explosion overpressure were measured. The intensity of the far-field explosion overpressure was estimated based on the extent of damage to buildings. The results demonstrated that the shock waves generated by a pipeline rupture indicate an extremely strong directional effect in the near-field, and their measured speeds were similar to the speeds calculated from theory. Not all of the gas energy participates in the explosion of a long pipeline, and an equation is established to calculate the gas energy involved in a pipeline blast. The TNT equivalency approach was used to calculate the explosion overpressure, and the impulse generated by the pipeline rupture and its applicability were discussed.

“…Chorowski et al . studied the bursting process of pressurized vessels using numerical simulation and determined that when the vessels cracked more slowly, the time needed to form an effective shock wave was greater, and the intensity of the leading shock was weaker. Geng et al .…”
