<title>Oil spreading in the deep sea and search for methods of discovering oil pollution under the sea surface</title>

Abstract: This report is dealing with the problem of estimation the damages to environment caused by the crude oil (or oil products) spills from the underwater sources. The peculiarities ofthe oil movement caused by flotation and turbulence in the deep sea were considered on the basis of assumption that the oil dispersed on the separate drops.It is showed that lthe oil which coming to the surface is divided into separate clasters in accordance with sizes of drops.The mathematical expressions were obtained that permited … Show more

“…If origin of coordinate axes lies in the source of drops on the depth -h, xaxis is directed along current and z -axis is directed upwards to the sea surface, then it is possible to write the partial differential equation of oil drops spreading in the following way: On basis the approximation of experimental data for the oil drops in water by nonlinear regression the empirical formula was received: W = 0,1 4(g * Vy/y )°' *°'° * (2) In this formula: d1 -drop diameter, m, (d1 2.2*lO 3m), y5-specific weight of sea water, kg / m -difference of oil and sea water specific weight, kg / m v5 -kinematics viscosity of the sea water, m2/s. It is not difficult to solve the equation ( 1 ) by known for following boundary conditions:…”
