基于CE/SE方法的铝粉尘爆轰二维两相数值计算
Two-dimension Two-phase-flow Numerical Simulation of Aluminum-dust Detonation Based on CE/SE Method
摘要
Abstract
Two-dimension two-phase model of aluminum dust-air detonation was created, A numerical scheme for deflagration-to-detonation transition process of aluminum dust was induced according to the theory of CE/SE method. The internal flow-field of aluminum-dust detonation tube was studied by CE/SE method. Pressure effect,changes of temperature and particle size were analyzed in the detonation tube. The influence of crash and reflex of aluminum dust-air combustion wave in the tube on explosion process was discussed. The numerical results show that wave fronts of temperature and pressure are coupled well in the detonation tube. Detonation wave formed by aluminum and air can spread themselves. The results provide some theoretical foundation for aluminum-dust detonation research.关键词
