Influence of air supply pressure over atomization particle size by air-water spray

air-water spray；atomization particle size；air supply pressure

In order to study atomization particle size of air-water spray，this paper，based on dust suppression system of spray underground simulation roadway，uses the Winner319 particle size analyzer to measure the atomization particle size at different air supply pressures under the condition of constant water supply pressure．The experimental results show that，When the water supply pressure is constant, as the gas-liquid pressure ratio increases, the gas flow rate gradually increases, the water flow rate gradually decreases, the fog field D50 and D [3,2] gradually decrease, and the optical concentration gradually decreases.
