CFD numerical simulation and experiment of the water air rotating jet flow dust controlling system on the comprehensive mechanized mining faces
To improve the dust controlling effects on the comprehensive mechanized mining faces,a new dustcontrolling method on the mining faces,the waterair rotating jet flow dustcontrolling system was proposed.The mechanism of the dustcontrolling system was analyzed,the site actual application
effects was experimented,and CFD numerical simulation was carried through the waterair rotating jet flow dustcontrolling system and the traditional directcurrent supply air dustcontrolling system on the mining faces.The result show that the system not only has a good atomization result,but
also can form rotating waterair curtain to prevent the dust from spreading quickly and polluting the entire roadway efficiently,and improves the dust controlling effects evidently.
