摘要


本研究目的為利用流體力學方法分析空氣噴嘴內部流場特性,利用求解動量、能量、連續方程式以及紊流模型來解析三維穩態黏性可壓縮噴嘴內部流場。本研究進行五種不同型式之圓管空氣噴嘴內部流場計算,以分析噴嘴型態對於內部流場特性的影響。此外本研究對其中兩型噴嘴進行紗線交絡實驗,求得紗線的交絡與牢度特性,並與計算結果進行比對驗證。本研究發現紗線交絡密度與氣道中軸向渦度有正向關係。

This paper employs the methods of computational fluid dynamics to simulate the internal flow field of Air-Jet nozzles to analyze the interlacing characteristics of yarn processed in cylindrical nozzles. The three-dimensional turbulent compressible flow field inside Air-Jet nozzles is calculated by solving the continuity, momentum and energy equations incorporated with a turbulence model. Additionally the yarn characteristics in two cylindrical nozzles are measured experimentally. It is found that the interlacing density of yarn has a linear dependence on the axial vorticity of air flow inside the nozzle.
