Abstract
Periodic two-dimensional waves on the surface of a flowing film are generally unstable. We have investigated their breakdown experimentally to determine the process by which film flows undergo a transition to spatiotemporal chaos. The two-dimensional secondary instabilities studied here are convective (like the primary instability); both subharmonic and sideband instabilities occur, but in different ranges of frequency.Keywords
