【 摘 要 】

A model of hydrodynamics of a two-phase liquid-solid system is formulated, in which forces of interphase dynamic interactions are taken into account. A scenario on distributions of insoluble solid particles emerging from an area source at the bottom of a lake in a stratified medium is considered. A calculation is performed in a three-dimensional statement taking into account the basic parameters of Lake Baikal. The results of the numerical simulation under winter conditions have shown that the two-phase system has a complex behaviour in space and time. The presence of solid particles strongly affects the hydrodynamics of the system and serves as a trigger for deep convection.
