摘要：
The improved numerical models based on the algebraic representations of the Reynolds stresses and fluxes and the use of the differential equation for the transfer of the dispersion of fluctuations of the vertical velocity component are considered for describing the processes of a vertical turbulent exchange in a stably stratified reservoir. Numerical modelling of the penetration of a turbulent layer of a mixed fluid in a linearly stratified medium under the action of constant shear stress is carried out. Computational results agree well with known experimental data and point to a substantial influence of the anisotropy of the flow on its main characteristics.
