Water Mist and Radiation Interactions: Application to a Water Curtain Used as a Radiative Shield

Abstract

A numerical simulation has been carried out on a water curtain used as a radiative shield against a source of thermal radiation. An Eulerian-Lagrangian code for the dynamics of the mist is combined to a Monte Carlo simulation of the radiative transfer in the air-droplet medium. Various attenuation efficiencies have been evaluated through comparisons on an academic reference case where multiple injections are generated on a line in order to build a water curtain. The aim of this study is to pinpoint more efficient configurations improving the radiative attenuation in saving the used water amount.
