Experiment Study of High Pressure Air Micro-pore Jet's Broken Dispersion Effect on Bulk Powder

  • 摘要: 针对堆积粉料的破散性问题,在设计和构建高压气体射流冲击试验装置的基础上,开展了射流形态、射流喷距和射流冲击实验,探讨了射流压强、喷距、时间、喷嘴形式及喷嘴个数对堆积粉料的破散效果。试验结果表明,当微孔喷嘴直径为0.5 mm时,相同条件下9孔喷嘴的冲击坑体积约为单孔喷嘴的5倍、穿透深度约为单孔的1.5倍。在综合考虑冲击性能、经济成本等因素时,对于孔径为0.5 mm的单孔喷嘴,其最佳工艺参数为喷距20 mm、压强0.5 MPa;最后采用Fluent模拟了单孔喷嘴的冲击过程,得到的仿真结果与实验结果两者之间非常吻合。
