ПРОГНОЗНОЕ МОДЕЛИРОВАНИЕ ПЕРЕНОСА СУСПЕНЗИЙ ПРИ РАЗЛИЧНЫХ СЦЕНАРИЯХ ИЗВЛЕЧЕНИЯ ЖЕЛЕЗОМАРГАНЦЕВЫХ КОНКРЕЦИЙ СО ДНА ТИХОГО ОКЕАНА

Abstract

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.

Highlights

The world's oceans are beginning to play an increasing role in environmental and climatological problems on Earth
More than 100 years ago, deposits of iron-manganese nodules (IMN) were discovered, which contain more than 30 elements of the periodic table, most of which are extremely rare on land on an industrially significant scale
It is well known that the study of issues related to the consequences of industrial extraction of minerals from the ocean floor, in particular, iron-manganese nodules (IMN), is an important scientific and practical problem that is in the focus of the world scientific community

Summary

Introduction

The world's oceans are beginning to play an increasing role in environmental and climatological problems on Earth. The suspensions propagation model having complex granulometric composition, capable of interacting in an aqueous medium, takes into account the suspensions microturbulent diffusion caused by the aqueous medium turbulent movement and the suspensions convection caused by the circulating (advective) movement of water mass in the ocean; suspensions gravitational deposition (under the gravity influence); mutual transitions between different fractions that make up the suspension (the combination of particles into larger ones and their decay); the interaction of particles with the bottom and with the free surface.
