On the question of optimization of the oil slick biodestruction in the bodies of water

We propose the system of nonlinear partial differential equations of parabolic type that describes the processes of oil pollution of water surface and bacterial degradation of this contamination. Problem of the parametric optimization of the acceleration process of degradation of the oil pollution is solved using this model. Optimality criterion is to minimize the time spent on destruction of oil pollution. Coefficient, characterizing the rate of population growth of bacteria, is selected as control parameter. Research is conducted using linearization of functions from the right-hand side of an equation in the neighborhood of solutions having practical significance. Also using the simplified model we obtain the formula that allows to predict the time for necessary destruction level progressing. Checking the results obtained for the linear equations is made using MATLAB. A comparison of experimental data and the calculated values is carried on to show the suggested model adequacy.
