Статья посвящена математическому моделированию распространения взвесей в восточной части Тихого океана для различных сценариев извлечения железомарганцевых конкреций. Модель распространения взвесей, имеющих сложный гранулометрический состав, способных взаимодействовать в водной среде, учитывает микротурбулентную диффузию взвесей, обусловленную турбулентным движением водной среды и конвекцию взвесей, вызванную адвективным движением водных масс в океане; гравитационное осаждение взвесей под действием на силы тяжести; взаимные переходы между различными фракциями, составляющими взвесь; взаимодействие частиц со дном и со свободной поверхностью.

The article is devoted to the suspensions’ distribution mathematical modeling in the Eastern Pacific Ocean for various scenarios for the ferromanganese nodules extraction. The suspensions propagation model with complex granulometric composition that can interact in an aqueous medium takes into account the suspensions microturbulent diffusion caused by the turbulent aqueous medium movement and the suspensions convection caused by the advective movement of water mass in the ocean; gravitational suspensions deposition under the gravity influence; mutual transitions between different fractions that make up the suspension; interaction of particles with the bottom and with the free surface.
