Abstract:
The w hole process of ex plosive dispersal and liquid-air cloud format ion w as divided into two regimes. For the f irst regime, a one-dimensional sing le phase model w as presented to depict the mot ion of gaseous detonat ion products and liquid fuel. And a moving boundary method w as used to t reat the outer boundary of gaseous products. For the second regime, a tw o-phase flow model w as presented to depict the interact ion of liquid and gas. The ex ternal shape of ex panding fue-l air cloud computed by numerical simulat ion is in g ood agreement w ith that of the measured. The variation of physical parameters in cloud is also show n by numerical simulation.
