The transition from laminar to turbulent flow in the radial liquid film flow on a rotating disk is studied experimentally. The flow is generated by letting water discharge from a cylindrical opening between a horizontally placed rotating disk and a circular nozzle into the atmosphere along the upper surface of the disk. High speed photographs of the process of transition are presented. Moreover, the influence of the rotational frequency of the disk on the radius occurring the transition is investigated. The results show that, while the rotation of disk suppresses the laminar-turbulent transition as long as the circumferential velocity is relatively small to the radial velocity, it promotes the transition when the circumferential velocity becomes large.
