该文利用Gambit和Fluent对伺服阀衔铁组件的啸叫问题进行了CFD分析,模拟计算了产品内部油路结构的流固耦合,发现在伺服阀衔铁组件啸叫的时候,流体在产品内部的产生了一明显的狭长负压区,改变产品内部结构再次进行CFD的模拟计算,负压区消失,对该结构的产品进行实际的通压通液测试,伺服阀啸叫的问题得到解决。 相似文献

Cyclone separators are one of the device used in power plant for long time; so many developments have been made in geometry, orientation and entry angle. In the present work an attempt is made with replacement of single inlet with double inlet. Computational analysis is done with Fluent 6.3.26 with Gambit 2.4.6 mesh generation using Cooper meshing facility. Eulerian–Lagrangian approach is adopted in the simulation with air as a working fluid and assumed to have continuous properties (Continuum). The collection efficiency of single and double inlet separator is studied using Lapple model, and it is found that there is an increase of 13.2% in collection efficiency for cyclone separator with double inlet. It is also found that higher inlet velocities are possible with double inlet separator without wall erosion when compared to single inlet separator. 相似文献
