Modelling of oil spill spread
2016
This paper presents a model of oil spill spread taking into account the evaporation of light, neutral and non-evaporating pseudofractions of oil spots, dissolution of oil spots and biodegradation. An approximation of the diffusion-convection problem is performed based on schemes of high order of accuracy. An experimental implementation, designed to model possible ecosystem scenarios of shallow waters for oil spills in the Azov-Black Sea basin, is presented. Based on a multi-processor architecture, decomposition methods of grid domains have been employed for computationally expensive diffusion-convection tasks in the context of a parallel implementation. The maximum speed-up achieved is by a factor of about 230 based on a configuration of 512 computational nodes.
