Structural fragments and explosions in industrial facilities: Part II - Projectile trajectory and probability of impact

Résumé

When dealing with risk analysis, due to industrial explosions, it is required to collect and develop a detailed knowledge about the source terms (features of the generated fragments), the impact terms (fragment trajectory) as well as the target/projectile interaction. The present paper focuses on the fragment trajectory and the possible impact over industrial targets erected in the vicinity. A preliminary study (Part 1) has been devoted to develop the probabilistic distributions for the source terms. According to the fragment features at their departure. from the source, the trajectory is evaluated under the combined effects of the inertia, the gravitation and the aerodynamics (drag and lift): translational as well as the rotational movements of the fragments are analyzed Three fragment shapes, generated by either cylindrical or spherical vessels explosions, are investigated end-cap, oblong end-cap and plate. For illustrative purposes. three target shapes are considered: cylindrical, ellipsoidal or cubic vessels that can be impacted by the generated fragments.
