摘 要:
旋转射流在工程上有着广泛的应用。利用FLUENT软件,对导叶加旋法产生的自由淹没气体旋转射流流场进行了数值模拟计算,从计算结果中得出不同喷距断面上的速度和压力分布特性,以及中心速度的衰减规律,对其流场结构与形态也有了深入的了解。将数值模拟结果与试验结果进行了对比,得出了较为一致的结论,为旋转射流的工程应用提供了强有力的理论依据。[著者文摘]

Abstract:
Swirling jets has extensive application on engineering. FLUENT software is utilized to simulate free and submerged swirling gas jets＇ flow field in numerical simulation. From the computational results, some plots of velocity and pressure properties in different sections of swirling gas jets＇ flow field are drawn out. The reducing regulation of the center velocity is acquired. Further realizations of flow field＇ s structure and shape are clearer. The computational results and experimental results agrees well through comparing. These conclusions can be applied on engineering field.[著者文摘]
