Abstract: The sonic boom atomization mechanism was applied to design a nozzle based on the Laval aerodynamics principle. The designed nozzle was simulated on the Fluent platform and the performance of the nozzles was evaluated on a test platform. The different parameters, including the flow characteristics, atomization characteristics, and dust reduction efficiency of the nozzle were analyzed under different air-water conditions. The obtained results show that under the same air and water pressure conditions, the size probability distribution peak, particle size distribution range, and median diameter of the droplet are smaller than those of an internal mixing nozzle. The sonic boom atomization nozzle consumes less water compared to traditional nozzles. After the installation of the sonic boom fog screen dust reduction system in the return air channel, the average values of total dust concentration and respiratory dust concentration were reduced by 91.26% and 90.16%, respectively. The obtained results indicate that sonic boom atomization nozzles can realize water saving and efficient dust reduction in underground coal mines.
