| 摘 要： | 利用Fluent对4种不同孔型的辅助喷嘴进行了模拟求解，得出了湍流状态下辅助喷嘴管内流体的速度场，从微观上分析了辅助喷嘴内部的气体流动情况。对比分析了喷孔形状对辅助喷嘴喷出气流效果的影响。数值计算结果表明，在相同供气压力下四种孔型的辅助喷嘴气流射出能力依次为：7圆孔型>矩形孔型>双圆孔型>单圆孔型。与实验结果进行比较发现，数值模拟具有很高的可靠性。

Analysis of assistant nozzle with different orifice-form of air-jet loom based on FLUENT |
| |
| Abstract: | Simulation solutions to assistant nozzle with four orifice-form was done based on Fluent．The flow field velocity in the state of turbulence were obtained, and the inside flow field of assistant nozzle is microcosmically described．Influence of the orifice-form to the ejecting flow field was analyzed．According to the result of numerical calculation，supplied with the same air-pressure，the ejecting capacity of four orifice-form assistant nozzle took turns7 circular orifice > rectangular orifice > circular twin-orifice > single circular orifice．Compared with the experiment result，it was proven that the numerical simulation has a high reliability． |
