      A semiempirical model of gravitational mixing is considered with eguation for turbulent kinetic energy. The model includes three constants. Model properties are investigated on self-similar solution for incompressible fluids. Linear dependence of mixing effective width on Atwood number is ascertained. A finite-difference method of solution of equations is given for general, non-self-similar case. A solution is derived for compressible gases with mixing for an automodel problem with two energy release regions.
