Abstract: | The evolution of a certain class of arbitrary-amplitude perturbations in a stratified binary mixture is investigated analytically and numerically. The radical differences between the process in question and the process of hydrostatic adaptation in an ordinary single-component medium are demonstrated. In particular, a long-life “wake“ with nonzero temperature and admixture concentration perturbations that compensate one another in the density field may be formed when the process is completed. The slow process of dissipation of this wake, associated with heat and mass transfer, is investigated. |
