“…The TM problem on a plane interface between two incompressible liquids under the effect of alternating-sign acceleration which at the initial phase creates an unstable situation (this phase is considered above) and at the following phase a stable one is considered. This problem has been experimentally studied and described in [28,29]; and its numerical investigation is described in [30][31][32][33][34][35].…”

“…However, the calculations of [30] performed using DNS in the one-liquid approximation and of [31] performed using the k-ε turbulence model failed to describe the separation process. Only the two-liquid approach used in [32][33][34][35] gave a positive result.…”

One contribution of 13 to a Theme Issue 'Turbulent mixing and beyond: non-equilibrium processes from atomistic to astrophysical scales II' . The results of three-dimensional numerical simulations of turbulent flows obtained by various authors are reviewed. The paper considers the turbulent mixing (TM) process caused by the development of the main types of instabilities: those due to gravitation (with either a fixed or an alternating-sign acceleration), shift and shock waves. The problem of a buoyant jet is described as an example of the mixed-type problem. Comparison is made with experimental data on the TM zone width, profiles of density, velocity and turbulent energy and degree of homogeneity.
