abstract
Experiments which demonstrate two distinct subharmonic transition mechanisms are described. One mechanism is a resonant triad interaction and the other is a secondary instability of the streamwise periodic flow to three dimensional disturbances. Flow visualization with smoke wire streak lines and hot wire anemometer data are used to support these conclusions. The results are compared with previous experimental work and the relevant theoretical models. (A)
