Abstract

The analysis of heating and evaporation of droplets of the sprayed water by the radiation of the seat of fire is made. Influence of these processes on the shielding properties of water curtains is investigated. The calculations for the typical modes of thermal shielding are executed and graphic dependences of the parameters characterizing evaporation of droplets are received.
