Investigation of convective heat and mass transfer in northern reservoirs using an eddy-resolving model

This paper presents a mathematical formulation of the problem of thermodynamic interaction between a reservoir with supercooled bottom and ice cover on the free surface. Turbulent flows with coherent structures was simulated using the equations of thermohydrodynamics in the Boussinesq approximation in which the average (uniform along the horizontal) and convective (large eddies) components are distinguished. Motions of subgrid scales are described using a one-parameter model for the kinetic energy of turbulence. The applicability of models of various classes for calculating vertical heat transfer in deep-water reservoirs above permafrost zones are discussed.
