| Popis: | Methods are presented for the analysis of sounding optical beam intensity variations at the exit of a nonstationary nonequilibrium path with the use of the superstatistics and nonextensive statistical mechanics. The connections of the first and the second moments of the experimentally recorded distribution functions of the intensity scintillations inside the subapertures of the output beam profile were applied to derive the models for nonequilibrium flows as well as the hypotheses about the distributions of the temperature and aerodynamic flow phase states over the path. |
