IS LAMINAR-FLOW IN A CYLINDRICAL CONTAINER WITH A ROTATING COVER A BATCHELOR OR STEWARTSON-TYPE SOLUTION

Bertela and Gori (1982) have solved the flow of an incompressible viscous fluid inside a cylindrical container with a rotating cover. Some results are here reviewed in order to detect whether they exhibit any similarity to the so called Batchelor or Stewartson-type solutions for two infinite coaxial disks. The discussed numerical results seem to support the following statement: for a cylindrical container with a fixed radius the Batchelor-type solution occurs when the angular speed of the rotating disk is high enough; the Stewartson mode is found for a large enough distance between the top and bottom disks.
