【摘要】 建立了超音速气固两相分离装置试验系统,在室温和不同喷管进口全压下,对空心玻璃珠颗粒的分离效率进行了试验研究.试验结果表明:当喷管进口全压在482~537 kPa范围时,超音速气固两相分离试验装置对Sauter平均直径9.84μm颗粒的总分离效率为57.83%~67.28%,对直径大于8.31μm颗粒的分离效率为75.73%~80.52%,对直径在15μm以上颗粒的分离效率为96%~100%,表明颗粒直径越大,分离效率越高.由此可见,超音速气固两相分离方法是可行的.试验研究为超音速气固两相分离技术的进一步深入研究和应用提供了有用的参考.更多还原

【Abstract】 An experimental system for separation of gas and solid two phases in supersonic gas flow was established.Separation efficiencies of hollow glass beads were measured under room temperature and different nozzle inlet total pressures from 482 kPa to 537 kPa.The experimental results show that the 57.83% - 67.28% particles with a Sauter average diameter of 9.84 μm can be separated by the experimental device.the 75.73% - 80.52% particles with diameters above 8.31 μm and the 96% - 100% particles with diameters above 15 μm can also be separated.Bigger particles correspond to higher separation efficiency.The present method for separation of gas and solid two phases in supersonic gas flow is successful and feasible.更多还原
