Analysis of The Effect of Atomizer Spray Refrigeration in High-temperature Caving Face by Stochastic Model

摘要

The temperature field and the coupling mechanism of the airflow in transportation channel was analysed by the currency software FLUETN, based on the conservation principle, by using the single-phasic multicomponent model. The simulation result was also compared with the temperature measured in mine. Then the atomizer spray refrigeration process of two schemes were simulated, considered the turbulent diffusing effect of the droplet and combined with the gas-droplet two direction coupling stochastic model, to forecast how pulverization droplets affect the temperature field of the airflow. The oretics gist for designing the pulverization refrigeration project is supplied in the paper.
