Explosively Dispersed Liquids. Part 1. Dispersion Model
Abstract
A preliminary analysis of the dispersion process of liquid droplets into an aerosol cloud is presented. This assessment of the complex phenomena is not all encompassing, but is believed to shed some light upon the behavior of the various mechanisms which govern the expansion of explosively dispersed liquids. This analysis does provide a basic understanding, and provides data for preliminary design estimates. The equations presented are based on the concept of a fluid piston in the first three of four regimes of motion. This fluid piston is essentially a gas bubble surrounded by a liquid shell. As the gas bubble expands it forces the liquid outward to form the characteristic explosive dispersion cloud. The fluid piston degenerates into discrete droplets, whose motion is governed by aerodynamic forces in Regime IV. These equations of motion were developed from experimental data collected with two different size devices. The agreement with this data indicates that scaling requirements are satisfied.
