The turbulent transition of a flow between two parallel walls and rotating circular disc was investigated theoretically. Since the distances between them are assumed to be very small, the viscosity of a fluid may be effective all over the space, and two components of the disturbing velocity seems to be very important to cause the transition in a flow and to be able to neglect the other component normal to the disc. A momentum equation can be introduced by integrating the equation of motion with respect to z, which is taken in the direction normal to the disc surface, from the disc to the wall. In this case two types of velocity distribution can be considered and the critical values of Reynolds number corresponding to each case were found. The experimental points obtained by Schultz-Grunow and Y. Kitani are found between these two theoretical ones.
