Simulation of Transfer and Spread of Pollutants into the Marine Environment Using a Probabilistic Model of Turbulence

Abstract

The paper describes the problem and specifies the key sources of marine pollution. A mathematical mode of particle transfer and settling as well as the parameters of environment turbulence are proposed. A 3D diffusion-advective model discussed in the paper was developed on the basis of “wandering particles” method with the use of random numbers generator for nondeterministic processes simulation. But it has a number of specific features as compared with similar models in practical setting of boundary conditions at water-air boundaries and water-bottom boundaries, description of turbulence of different scales, in taking into account the effects of the initial immersion of a heavy jet, in the effect of flocculation as well as taking into account non-conservatism of the impurity. Different simulation results are presented.
