|Abstract: ||By employing the method of multiple time scales, we derive here the transport equations for the primary amplitudes of resonantly interacting high-frequency waves propagating into a non-equilibrium gas flow. Evolutionary behavior of nonresonant wave modes culminating into shocks or no shocks, together with their asymptotic decay behavior, is studied. Effects of non-linearity, which are noticeable over times of order O(epsilon(-1)), are examined, and the model evolution equations for resonantly interacting multi-wave modes are derived. (c) 2005|
