| 摘 要： | 本文针对水力旋流器中存在着较强旋流，从而引起各向异性湍流流动的特点，以强旋流场的代数应力模型为基础，得出可模拟水力旋流器中液相湍流流动的各向异性的ｋ－ε模型，成功地计算出其流场中的速度分布，计算结果同用ＬＤＡ所测得的结果比较一致。

| Abstract: | A new mathematical model, which takes into account the anisotropic turbulence caused by the strong swirl, is developed based on the ASM model. The model equations are solved with the SIMPLER computer code, by taking the velocity profiles and the radial profiles of pressure as the output. The predicted velocity profiles show good agreement with the experimental data measured by a LDA. |
