Abstract

We propose a device which produces a high density cloud of spray that is consisted mostly of water micro droplets. The cloud automatically occurs when an electromagnetic pulse or/and shock wave from a close explosion matches the device. The ratio of absorbed energy of the dangerous shock wave depends on the density of the cloud and on its spreading speed as well as on the size and the mass of micro droplets. We have developed a mathematical model of physical processes in the Absorber. Numerical simulations show satisfactory assumption with our experimental data. Some recommendations are proposed for the Absorber efficiency optimization.
