摘要：

Numerical investigations are made on the source-sink flows in a rotating cylinder. A finite difference method is used to solve the time-dependent full Navier-Stokes equations to an incompressible, viscous and axisymmetric flow. Computations are carried out for three cases with different Ekman numbers and a fixed aspect ratio. Transient aspects of flows are discussed focusing on the developments of the Ekman layers on both disks, and the E1⁄4 layers vertically formed at the radii of a source and sink located on the upper and lower disk, respectively. Numerical results based on a similarity analysis of the nonlinear E1⁄4 layer agree well with the experimental ones. © 1978, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
