This article focuses on the interaction of thermal radiation with water droplets and creation mist for purpose evaluating decrease heat flux when positioning a curtain various parameters between source radiometer. The change parameters, affecting passing through radiation, was performed using five nozzles variable spray characteristics. For respective attenuation determined transmittance calculated. Water created high‐pressure pump different size orifice. measurement droplet time‐shift...
Determining the particle size distribution of water mist is necessary for a wide range industrial applications or experimental measurements. Particle defines ability to absorb heat, scatter heat radiation, inertize environment, reduce environmental dust, regulate odor, etc. The paper presents principle measuring droplet using laser diffraction and measurement procedure four hollow cone nozzles with orifice 400 µm, 500 600 µm 1000 µm. measurements were performed at distances 25 mm, 50 75 100...
Introduction . Tanks and tank farms are widespread in many constituent entities of the Russian Federation among most important elements model for production, treatment, transportation processing oil products. It is relevant both at global levels to ensure that fire safety arranged reduce highest risk according risk-based model. In context information communication technology (ICT) developments introduction ICT into operation management various facilities, over past decades advanced methods...
Abstract This article focuses on the interaction of infrared (IR) radiation with water droplets. The main objective is production mist in order evaluation reduction intensity IR radiation. In experiments described this paper, a set five different nozzles was used various spray characteristics. respective were gradually located between source and detector attenuation assessed. determined transmittance calculated for tested nozzles.
Currently, there is progressive use of fire protection systems that the high-pressure water mist. The extinguishing effect mist on flammable liquids not sufficiently elucidated. Therefore, experiments were designed to gain new knowledge about mechanism extinguishing.As a source pool fire, gasoline, kerosene, diesel and ethanol used. Flammable stored in circular steel container with diameter 165mm depth 12mm. was placed an enclosed room 2.7 x 2.7m 3m. In experiment, time extinguish measured...
