Abstract

In order to determine the flight distance of fragments in the explosion accident by liquefied petroleum gas storage tank, the prediction model for the flight distance of fragments in explosion was built based on dynamic principle and theoretical analysis.The numerical simulation and verification analysis were also carried out according to the data from some LPG explosion accident cases. The results show that the predicted values of the model are consistent with the accident data and the previous results of Monte-Carlo numerical simulation, and the model has good applicability to explosion accidents of spherical tank and cylindrical tank. The model can quickly and conveniently predict the damage range of the fragments in explosion.The prediction results can provide technical support for emergency departments to make rescue decisions, and it can also provide theoretical basis for the planning, construction and risk control of petrochemical parks.
