| Abstract: | Circular and spiral waves are observed in the flow between a rotating and a stationary disk. These waves are generated by
instabilities of the stationary disk boundary layer. This experimental work is devoted to their study by means of flow visualization
and measurements of the associated velocity fields. In particular, instantaneous velocity profiles are measured by ultrasonic
Doppler anemometry. The spatio-temporal characteristics of the waves are studied with the help of Fourier transforms of these
velocity signals.
