| Summary: | Title screen This article presents the results of experimental studies on the absorption of thermal radiation from an open flame by a water-based spray curtain. Two typical applications were simulated: the thermal purification of water from insoluble impurities and the thermal protection of objects from open flames. Mathematical processing and generalization of experimental data led to the development of prediction equations for estimating the required thickness of the spray curtain and concentration of solid particles in the water necessary to effectively reduce heat from the radiation source. The influence of the geometric dimensions of the curtain, speed, size, and volume concentration of droplets in the aerosol cloud, as well as the addition of solid impurities on the characteristics of thermal radiation absorption by the spray curtain has been established. It has been established that an increase in the lateral size of the aerosol flow to 0.1–0.3 m reduces the density of the radiant heat flux by 28–45 %, while bentonite slurry, which reduces the radiant heat flux by up to 20 %, is the most effective additive for thermal radiation absorption by a spray. Based on the results of the analysis of the experimental data, a mathematical model is developed for predicting optimal heat and mass transfer conditions. Using this model, a parametric study is performed that makes it possible to establish the necessary input parameters for intensifying the heat transfer of spray droplets with different contents of solid particles and thermal radiation Текстовый файл AM_Agreement |
