| description | The flammable gas volatilized from the storage medium in the tank will burn and explode under the action of an accidental ignition source. Tank explosions formed by the explosive shock wave, explosive debris will not only cause their own damage, but also on the safe operation of adjacent tanks to form a threat. Therefore, in this paper, the vertical dome roof tank is taken as the research object, the criteria of brittle fracture failure of tank materials are constructed, and the multi-field coupling calculation model of tank detonation based on TNT equivalent method is established, taking into account the fluid properties inside and outside the tank, the structure of implosion tank and adjacent tank. By analyzing the full time domain process of gas detonation in tanks under different influence factors, the response to implosion damage of tanks and adjacent tanks under the action of explosion shock wave overpressure and debris was obtained. With the increase of the liquid level, the overpressure and deformation of the shock wave of the detonation tank and adjacent tank decrease, and the type and number of fragments decrease. With the increase of the volume of the tank, the overpressure and stress of the shock wave become larger, the strain rate of the tank becomes larger, and brittle failure is more likely to occur. The types and number of fragments formed increase, but detonation fragments are not formed when the tank is full. The research results in this paper provide a theoretical basis and calculation method for preventing and controlling tank implosion accidents, as well as tank design and tank spacing layout. |
