Bifurcation Superstructure in a Model of Acoustic Turbulence

Abstract
A model of acoustic turbulence is investigated for its bifurcation structure by the calculation of spectral as well as ordinary bifurcation diagrams and (subharmonic) attractor maps. A superstructure resulting from nonlinear resonances is found with period-doubling Feigenbaum direct cascades and Grossmann inverse cascades as fine structure. Connected with the superstructure is a new family of periodic chaos with a different type of chaos belonging to each basic subharmonic period of oscillation.
