摘要: 在钢结构危险品储柜内开展可燃气体爆炸试验,运用FLACS数值模拟软件对危险品储柜内可燃气体爆炸火焰传播进行数值模拟研究,并将试验结果与数值模拟进行对比分析。研究结果表明,钢结构储柜内部气体爆炸试验火焰传播与数值模拟计算结果较为吻合。随着可燃气云体积的增大,火焰内部流场越来越复杂,且泄爆板打开后,内部火焰更加剧烈。仅当危险品储柜内部可燃气云达到一定规模时才会出现外部火焰,且外部火焰从距离气云较远的泄爆口泄出量要大于距离气云较近的泄爆口。

Abstract: Conducted combustible gas explosion tests inside steel storage cabinets for hazardous goods, used FLACS to conduct numerical simulation research on the flame propagation of combustible gas explosion inside hazardous goods storage cabinets, and compared and analyzed the test results with the numerical simulation. The research results indicate that the flame propagation in the gas explosion test inside the steel storage tank is in good agreement with the numerical simulation calculation results. As the volume of the combustible gas increases, the internal flow field of the flame becomes more complex, and after the release plate is opened, the internal flame becomes more intense; External flames only appear when the combustible gas cloud inside the storage cabinet reaches a certain scale, and the amount of external flames emitted from the vent located further away from the gas cloud is greater than that from the vent located closer to the gas cloud.

Key words: hazardous goods storage cabinet, gas explosion, flame propagation, numerical simulation
