Abstract

En 中文
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.
