Simulation and analysis of effect of LNG explosion in pipes
As a kind of superior clean energy,LNG is transmitted to gas fuel generator by means of pipes and pipes are vulnerable to potential safety hazards such as explosion in the process,therefore it is necessary to perform the numerical sim-ulation of LNG explosion in pipes.This study uses the software Ansys/Lsdyna to perform the methane explosion simulation and analyze the damage features with or without explosion suppression measures.Multiple conditions with different explo-sion pressure are introduced to study the distribution trend of the stress field,strain field and strain energy field and the con-clusion is drawn that the explosion pressure in burst cavity and the energy received by the terminal are positively correlated.It provides technical reference for follow-up LNG fuel system safety design.
