| 摘 要： | 利用κ—ε双方程湍流模型对自行设计的射流式增氧机内部流场进行了模拟，得到了流场内部各个参数的分布图，揭示了混合管内部的流动状态，为射流式增氧机的参数优化和性能预测提供了可靠的手段。通过对射流器仿真数据的分析，得出混合管与喷嘴截面积比的最佳值为2．33，并通过增氧试验验证，证明仿真结果与试验结果相吻合。

| Abstract: | The κ-ε two-equation turbulence model was applied to simulate the internal fluid field in a jet aerator designed by the authors. The parameter patterns within the fluid field revealed the flowing state in the mixing tube, which provided a reliable approach for parameter optimization and performance prediction of the jet aerator. The analysis of the data of numerical simulation indicated that the optimal area ratio was 2.33. The oxygen transfer experiment proved that the numerical simulation was in the same line with the experimental results. |
