摘要：

We study the first steps of ice formation in freshwater turbulent convection (frazil ice regime). We explore the sensitivity of the ice formation process to the set of non-dimensional parameters governing the system. We model the mixture of ice crystals and water as a two-phase medium composed of water and ice particles of fixed diameter. We use the Boussinesq approximation and we integrate numerically the set of equations making use of a numerical code based on second order finite difference. A dynamic LES model for the subgrid scales is used.
