对旋进球腔和球壳中的流体流动进行了数值求解，并与以前的解析表达式进行了比较。结果表明，近似的有效性的分析表达式扩展到更远的比可以预期的。然而，流场结构的细节与分析理论的假设有很大的偏差。驻波的情况下，发现足够薄的壳。文中还讨论了基本流不稳定性的一些结果。
Numerical solutions for fluid flows in precessing spherical cavities and spherical shells have been obtained and are compared with earlier analytical expressions. It is shown that the approximate validity of the analytical expressions extends further than could have been expected. The details of the flow structure exhibit significant departures, however, from the assumptions of the analytical theory. Standing waves are found in the case of sufficiently thin shells. Some results on instabilities of the basic flow are also discussed.
