采用基于Allen&Southwell方法的有限差分离散方法，求解了圆盘间径向不可压缩流动的涡量输运方程。该解决方案允许对所研究的雷诺数范围1≤Re≤300的流动进行详细的表征。在Re=60以上有分离现象，气泡尺寸随Re的增大而迅速增大。研究了流向和横向的压力和速度梯度，以解释观测到的现象。
The vorticity transport equation is solved for radial incompressible flow between disks by a finite-difference method with discretization based on the method of Allen & Southwell. The solution permits detailed characterization of the flow for the Reynolds number range investigated, 1 ≤ Re ≤ 300. Above Re = 60 separation is observed with the bubble size increasing rapidly with Re. The streamwise and transverse pressure and velocity gradients are examined to interpret the observed phenomena.
