An adaptive grid scheme controlling cell area is used to generated grids in the divergent section of symmetric annular nozzle, and the generated grids are used in the flowfield calculation through the uncoupled way. The elliptic equations are used to generate grids in three dimensional regions of FDN divergent section, the source terms used in the equations employ a mathematical form which is independent of the boundary shape and of the boundary grid point distribution, the free parameters contained in the source terms are determined by the two restraint conditions, the intersection angle of transverse grid lines with boundaries and the local curvature of the transverse grid lines at the boundaries, and the interior grid distribution controlled directly by the grid point distribution assigned on the boundaries is realized, it makes the grid more clustering near the nozzle wall. For the generated grids in the whole computational regions have a good smoothness and orthogonality, the accuracy of calculation in the flowfield is ensured.

流体自旋流器上端给入并在旋流器内形成强制旋转流，旋转流将颗粒按粒度和比重分为内外环层，当矿浆流动至锥体部分时，由于锥体的突然变向，阻力增大，颗粒群向下运动的趋势减缓，并在此形成旋转悬浮层，随着离心力场的减弱，重力作用越来越明显，由按粒度和比重分成的内外两层逐渐转化为按比重分选的上下两层，比重大的颗粒通过底流口排出，比重小的颗粒则通过溢流管排出，从而实现轻重颗粒间的分离。

Phase-lagged cyclic boundary condition is implemented by a novel method in conjunction with the developed sliding interface technique to accurately simulate the arbitrary pitch ratio rotor/stator interaction without any modifications of the physics of the problem. It's for the first time to compose the computational area into one structured grids including both rotor/stator of centrifugal or axial turbomachinery with arbitrary pitch ratio. This method can eliminate the iteration of boundary conditions on the sliding interface and calculate the unsteady flow within rotor and stator simultaneously.
