| 摘 要： | ＡＳＭ也进行了研究。研究的流场包括有约束的和自由的强涡旋流动。研究结果表明，二阶矩封闭模式在计算强涡旋湍流流动中很有效，代数模式则不能令人满意。计算结果可供燃烧室设计参考。

| Abstract: | Numerical computation of turbulent strongly-swirling in combustors is presented. Turbulence models examined are based on the transport equations of the Reynolds stresses, i.e., the second-moment closures. The particular flows in question include confined as well as free swirling situations where the swirl number is large. It is indicated that the second-moment closure models offer an effective means for predicting strongly swirling flows. In particular, the Isotropization of Production and Convection (IPC) model gives the best overall performance. The study directly serves for the improvement of combustor design. |
