Gas Leakage Simulation of Underground Integrated Pipe Gallery Based on Particle System
For the underground integrated pipe gallery containing natural gas pipelines,the current daily management of leakage accident risk mainly includes real-time monitoring,regular detection,emergency plan preparation and risk assessment by using various sensing devices,and sometimes emergency drills under different scenarios based on the deduction of disaster chain and fault tree.These management methods urgently need to scientifically simulate and deduce the micro process of risk evolution under the set scenario based on the model of gas leakage diffusion and lack process details and quantitative consequence assessment in the prediction and early warning of accident development.We use the particle system simulation method in the game engine Unity3D to simulate the natural gas leakage and diffusion process inside the pipe gallery based on a certain diffusion physical model and realize the construction of the pipe gallery model and the setting of particle system parameters.The temporal and spatial dynamic visualization of the leakage natural gas concentration distribution in the pipe gallery under different leakage scenarios is realized by setting the scenario parameters.The simulation method can provide quantitative scientific basis for emergency plan formulation,emergency drill and emergency rescue of natural gas leakage accident in underground integrated pipe gallery.
