Nonlinear response of driven systems in weak turbulence theory

PDF Version Also Available for Download.

Description

A method is presented for predicting the saturation levels and particle transport in weakly unstable systems where there are a discrete number of modes. Conditions are established for either steady state or pulsating responses when several modes are excited for cases where there is and there is not resonance overlap. The conditions for achieving different levels of saturation are discussed. Depending on details, the saturation level can be quite low, where only a small fraction of the available free energy is released to waves, or the saturation level can be quite high, with almost a complete conversion of free energy ... continued below

The conditions for achieving different levels of saturation are discussed. Depending on details, the saturation level can be quite low, where only a small fraction of the available free energy is released to waves, or the saturation level can be quite high, with almost a complete conversion of free energy to wave energy coupled with rapid transport.
