In this study, the effects of five coaxial triple swirler configurations on mass flow rate distribution, swirling flow structure, and Coanda flow formation to transition were investigated. The study utilized a numerical investigation with the Re-Normalization Group k-ε Turbulence model to simulate the internal and external flow field. An experimental setup was also provided to validate the numerical results using a Particle Image Velocimetry system. The swirling flow structure was classified into three categories: Coanda, Transient, and no-Coanda flows. Results showed that the transient swirling flow from the Coanda flow occurred with a slight change in the outer recess length, which can control the three flow categories. Also, the study found two types of swirling flow structures with cylindrical and bubble shapes with the change in the inner recess length, a key variable in controlling the swirling flow structure. Additionally, the study presented quantitative results to predict the formation of the Coanda flow using dimensionless parameters composed of momentum ratios of swirlers. Overall, the findings of this study provide valuable insights into the design and optimization of coaxial triple swirler configurations for practical applications.
本文研究了五种同轴三旋流器构型对质量流量分布、旋流结构和Coanda流形成转捩的影响。采用Re-Normalization Group k-ε湍流模型进行数值模拟。最后，利用粒子图像测速系统对数值结果进行了验证。旋流结构分为三种类型:康达流、瞬态流和无康达流。结果表明:Coanda气流产生的瞬态旋流，其外凹槽长度变化不大，可控制三种流动类型;此外，研究还发现了圆柱型和气泡型两种旋流结构，其内部凹槽长度是控制旋流结构的关键变量。此外，利用旋涡动量比的无量纲参数对康达流的形成进行了定量预测。总的来说，本研究的发现为实际应用中的同轴三旋流器配置的设计和优化提供了有价值的见解。
