Investigation on Impact Probability between Fragments from Horizontal Cylindrical Vessel Explosion and Spherical Objective

摘要：

Fragment projection, which is stochastic and destructive, is one of the major escalation vectors resulting in domino effect in chemical industry. Monte Carlo simulations and movement equations of the fragment were applied to explore the characteristics of its flight and threat to nearby items, the distribution of projectiles impact on the ground, which is compared to the accident data, was obtained with the probability density functions of random parameters reported in the literature. On this basis, the computation of the impact probability was improved, and the effects of the filling degree of source vessel, relative distance from the source, and the target volume on the probability of fragments from horizontal cylindrical vessel explosion impact on spherical tank were investigated when the objective was orientated in different sectors of horizontal departure angle. Research results show that a number of 2000 simulations provide a good convergence for the impact probability, which increases slowly according to the filling degree of the source and the target volume, decreases rapidly with the distance; moreover, the probability of impact in the sectors with horizontal departure angle
