中文摘要: |
为了研究喷孔数量对喷嘴内气流场的影响,应用FLUENT流体计算软件对喷嘴内部气流场进行数值模拟,并结合OriginPro对不同喷孔数量时喷嘴内部气流场状况进行比较和分析,深入解析喷孔数量对涡流场的影响。研究表明:喷孔数量对喷嘴内部气流场的特性影响较为明显,随着喷孔数量的增多,气流在喷嘴中形成的旋转运动增强,喷嘴入口处用以吸引纤维的负压也随之增大,对纱线的加捻特性也就越强。 |

ln order to studv the influence of orifice number on the flow field in the nozzle. the flow field inside the nozzle of air jet vortex spinning was simulated with FLUENT. and the flowing state was compared and analyzed under the different number of orifice with OriginPro 8 ,the influence of orifice number on the vortex flow field was deeply analyzed.The research showed that the airflow field in the nozzle was obviously influenced by the number of orifice, the rotational motion of the air flow in the nozzle was enhanced with the increasing of the orifice number, and the negative pressure sucking the fibers into the nozzle also increased at the entrance of the nozzle.twisting characteristic on the garn was also stronger. |
