EXPERIMENTS ON THE SUBHARMONIC ROUTE TO TURBULENCE IN BOUNDARY LAYERS. Conference Paper uri icon

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 streaklines and hot-wire anemometer data are used to support these conclusions. The results are compared with previous experimental work and the relevant theoretical models.
