In the risk assessment of domino accidents,fragment is one of the key factors,and it is urgently necessary to evaluate the damage to the target equipment caused by fragment impact.This paper establishes a numerical model of a horizontal storage tank subjected to impact by a head-shaped fragment based on the Coupled Eulerian-Lagrangian(CEL)method.The different phenomena presented by the tank under different filling states are analyzed.The results show that the internal fluid effect cannot be ignored when analyzing the impact of fragment on the tank.
