| Sumari: | Title screen The paper presents experimental research findings for the temperature reduction of pyrolyzing and burning materials under typical indoor fire conditions when model fires are sprayed with varying water discharge density. The most typical combustible materials found in premises were considered. Two methods of extinguishing a model fire were investigated: continuous and cycling water mist discharge to the combustion zone. The velocities and average sizes of droplets in the aerosol flow were recorded of the experiments. Shadow Photography and Particle Image Velocimetry methods were used to record the aerosol parameters. An optical complex including a Quantel EverGreen 200 pulsed Nd:YAG laser and an ImperX IGV B2020M CCD camera was used. The findings revealed that a selective water supply system operation is required to suppress the combustion of different categories of materials. The values of the fire suppression performance index were calculated from the results of the experiments. Режим доступа: по договору с организацией-держателем ресурса |
