Abstract:
Objective To establish a model of chlorine tank leakage and diffusion so that to provide an effective basis for evacuation of large-scale crowd in the accident.
Methods Using the fluent fluid software to simulate chlorine tank leakage situation in Xi'an chemical industry company. Through the determination of the chlorine leakage speed, the choice of the basic solution, the establishment of the simulation area net, and the entrusting of boundary condition, the chlorine leakage diffusion model was constructed.
Results The established model successfully simulated chlorine gas leakage situation in different wind speed (1.5 m/s, 4.5 m/s), and dangerous regions during the chlorine leakage could be divided into:injury area (radius 1 000 m), serious injury area (radius 500 m), and fatal area.
Conclusion The forecast method may provide emergency response for toxic substances leakage accident.
