doi:10.3969/j.issn.1000-1093.2014.07.005

Abstract

Abstract: The solid-liquid mixed fuel explodes to form a fuel air cloud. The detonation strength depends largely on the air cloud state. The cloud distribution is the base of the design of cloud detonation devices. The dispersal process of solid-liquid mixed fuel is investigated by numerical simulation, and a numerical simulation method of solid-liquid mixed fuel is explored. The diffusion process of fuel dispersal in space and time are obtained. The radial dispersal velocity, cloud range and turbulent diffusion process in simulation agree well with the experimental results. The results show that the numerical model established in this study can simulate the dispersal process of the solid-liquid mixed fuel, which opens a new way of research for the optimal design of FAE devices.

Key words: ordnance science and technology, fuel air explosive, dispersal, numerical simulation, radial velocity
