| 摘要: |
| 将雷诺应力模型与欧拉分析方法相结合,对切流式单、双入口旋流器内的单相和两相流场进行模拟。模拟结果表明:与双入口旋流器比较,单入口旋流器内流场存在明显偏心现象,并且速度分布和湍流参数均存在偏差,流场很不稳定;对于油水两相流场,双入口旋流器的油相和水相体积分数径向变化梯度更大,油相更倾向于向轴心移动形成油核;双入口旋流器的工作性能优于单入口旋流器;试验结果验证了模拟结果的正确性。 |

| Abstract: |
| RSM and Euler method were combined to study the single phase and two phase flow field in tangential hydrocyclones. The results show that compared with double inlet hydrocyclone, single inlet hydrocyclone had eccentricity in the flow field, and there were differences in velocities and turbulent parameters, and the flow field was unstable. For the oil water flow, the radial gradients of volume fractions of oil and water in double inlet hydrocyclone were larger. The oil was more inclined to move to the axis and formed oil core. The work performance of double inlet hydrocyclone was better than that of single inlet hydrocyclone, and the correctness of the simulation was verified. |
