本文使用弱非线性、非轴对称扰功波的孤立波模型模拟螺旋型涡破裂。

The solitary wave theory of the weakly nonlinear, non-axisymmetric disturbances is used to model the spiral vortex breakdown.

结果表明，提升管内气、固两相沿轴向、径向和切线方向的流动不均匀，并非完全对称流动，而以S型螺旋形上升流动。

The simulation results showed that the flow of gas-solid two-phase was non-uniform in axial, radial and tangential directions, and was not symmetric flow as expected, but was up in S-type form.
