THREE-DRIFT-WAVE INTERACTION AT FINITE PARALLEL WAVELENGTH - BIFURCATIONS AND TRANSITION TO TURBULENCE
The generic properties of the nonlinear interaction of three drift waves with finite kappa-// are investigated. The different types of stationary or quasistationary states are characterized by the bifurcation diagram in gamma-1,kappa parameter space, where gamma-1 measures the mode excitation and kappa the parallel wavenumber. The transition to turbulence corresponds exactly to the Ruelle-Takens picture: steady state -> periodic solution -> doubly periodic solution -> turbulence, in contrast to the period doubling route usually observed in low dimensional dynamic systems. The transition to kappa-// = 0, the model of Horton and Terry (Phys. Fluids 25, 491 (1982)), occurs at very small values of kappa-//.
