Description
The technical field is as follows:
the invention relates to the technical field of explosion simulation, in particular to a method for testing the diffusion of a toxic substance under the action of explosion.
Background art:
in recent years, the continuous dangerous chemical explosion accidents are integrated with 'burning, explosion and toxicity', and are various in types, large in quantity and serious in harm. In the accident rescue process, the spreading condition of the toxicant under the action of explosion is not clear, the concentration distribution and the law of the toxicant are not mastered, the chemical hazard type and the hazard degree can be only roughly judged, and the accurate protection is difficult to carry out, so that the rescue work progress is slow. The process of diffusion of poisons under the action of an explosion can be roughly two stages: an explosion dispersion section and a cloud dispersion section. The explosion dispersion section refers to that the poison is strongly thrown under the action of shock waves, and the cloud cluster dispersion section refers to that the poison cloud cluster overcomes the gravity and the rising resistance under the action of buoyancy and performs thermal lifting movement relative to the atmosphere. The strong shock wave of the explosion dispersion section plays a leading role in the diffusion of poisons, and the damage in the explosion dispersion range is the most serious and is the rescue core area. The explosion effect directly affects the diameter and range of the primary cloud cluster, the aerosol particle size and the concentration distribution of the poison in the cloud cluster, so that all items after the explosion dispersion section is finished are the initial conditions of the cloud cluster diffusion section.
At present, researchers in relevant fields at home and abroad mostly assume that the poison is continuously released at a constant speed when studying the spread of the poison, namely, the situation under the action of explosion is not considered. When the poison diffusion under the action of explosion is researched, due to the complexity of the explosion process, the poison in the primary cloud cluster after explosion is generally assumed to be uniformly distributed, and a corresponding numerical model and a corresponding calculation method are established according to the assumption, although the diffusion tendency of the cloud cluster after explosion can be approximately reflected, the error between the calculated value and the actual poison cloud cluster diffusion value is large, and the calculation method is not beneficial to being used in the actual rescue process.
