Asymptotic laws of the propagation of weak nonlinear waves in a relaxing gas under the effect of external radiation
Abstract
Criteria are obtained for the breaking of nonlinear wave fronts during propagation in a gas with relaxation of vibrational degrees of freedom under the effect of external radiation. In particular, it is shown that all rarefaction waves are attenuated, compression waves are broken during a finite or an infinite period of time (depending on the initial wave intensity), and all other waves are attenuated. The results are explained in terms of relaxation processes in a gas.
