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。
RSM and Euler method were combined to study the single-phase and two-phase flow field in tangential hydrocy- clones. 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.
