“…For example, in situ burning is an effective way to clean up thick oil slicks [2][3][4], and predicting the initial spreading area is of great importance to arrange containment boom in this method [2]. However, the early spreading of crude oil is difficult to predict accurately by the simplified theoretical solutions [5][6][7][8][9] or experimental summaries [5,[9][10][11] because it is a complicated multiphase flow, influenced by manners of spilling, ship motion, wave, wind, current, etc.…”

Numerical simulation of free surface multi-fluid flow is a challenging problem owning to the interaction between deformed interface and free surface. In this paper, a multiphase particle solver (free surface multiphase moving particle semi-implicit method, FS-MMPS) is developed to predict the early spreading flow of spilled oil where exist the oil-water interface and air-oil/air-water free surface. First, a multiphase virtual particle model is proposed to substitute the inaccurate free surface boundary condition for multiphase flow in conventional MPS methods. Specifically, virtual particles of different liquid phases are compensated outside free surface so that the pressure of free surface particles can be solved from pressure Poisson equation, thereby improving the accuracy of multi-fluid interaction at free surface. Meanwhile, a pressure gradient model based on the coupling of Taylor series expansion and dynamic specification of particle stabilizing term (PST) is proposed to simultaneously enhance accuracy and depress instability caused by multiphase virtual particles. Experiments of early spreading of thick oil slicks and continuous oil spill from a damaged tank are conducted for validation and demonstration of the accuracy and

“…The main characteristics of the oil film will be its radius and thickness. The process is described using the mass conservation equation for the elemental volume of an oil film and the equation of motion of a viscous Newtonian fluid [15]. The equation of mass conservation for the mathematical model of the process under consideration in the axisymmetric case can be represented as 1The equation of fluid motion is 2where h is oil film thickness, m; u is film speed averaged over film thickness, m/sec; τ is shear stress at the bottom of the film; g is acceleration of gravity, m/s 2…”

The problem of intensive pollution of the Caspian Sea has been continued to be one of the most significant and serious for the region. The rising of pollution level of the Caspian Sea coast with oil hydrocarbons has a particular concern. The purpose of this paper is to assess the pollution degree of the Caspian coast with petroleum hydrocarbons. The idea of the author is to provide a comprehensive analysis of the environmental destructive factors of the oil production process on natural complexes, including the effect of chemical pollution of the water basin with petroleum hydrocarbons on local hydrobionts. Methods of mathematical modeling of the oil films spreading on the water surface aimed to the prediction of the influence area, and methods of toxicological studies and assessment of the dose-effect relationship have been used. It was determined that the waters of the Caspian Sea, associated with offshore oil production, are areas of increased environmental risk. In the cases the concentration of hydrocarbons is above 1 mg / l, physiological changes are observed in the majority of dominant groups of hydrobionts. Areas of increased risk level for marine ecosystems caused by gas and oil industry development are connected with north and west-south parts of the Caspian Sea. The obtained results can be used to develop programs to ensure the environmental safety of the studied region.

“…Consequently, it is now very likely that an ice-free Arctic Ocean, a so called 'Blue Ocean Event', will be realised by the mid-century unless there is a rapid reduction in greenhouse gas emissions (Notz and Stroeve, 2018). In response to the 'blue' Arctic Ocean, there has been a significant interest in developing northern shipping routes which can decrease journey lengths from Europe to Asia by up to 40% (Ho, 2010;Eguíluz et al, 2016;Kikkas andal., 2005, 2011;Gamzaev, 2009), with the consensus being that knowledge of oil droplet size distribution is fundamental to accurately model ocean oil spills (Nissanka and Yapa, 2018). There have also been several lab (Hesketh et al, 1991;Masutani and Adams, 2000;Tang and Masutani, 2003;Brandvik et al, 2013Brandvik et al, , 2014Wang et al, 2018) and field experiments (Johansen et al, 2003;Brandvik et al, 2010) which have generally focused on very high levels of pollution within a relatively short time frame from the release of oil.…”

Abstract. Sea ice albedo is an important component of the Earth’s climate and is affected by low background concentrations of oil droplets within the ice matrix that absorb solar radiation. In this study the albedo response of three different types of sea ice (multi-year, first-year, and melting sea ice) are calculated at increasing mass ratios (0–1000 ng g−1) of crude oil by using a coupled atmosphere-sea ice radiative-transfer model (TUV-snow) over the optical wavelengths 400–700 nm. The different types of quasi-infinite thickness sea ice exhibit different albedo responses to oil pollution, with a 1000 ng g−1 mass ratio of oil causing a decrease to 70.9 % in multi-year sea ice, 47.9 % in first-year sea ice, and 22 % in melting sea ice relative to the unpolluted albedo at a wavelength of 400 nm. The thickness of the sea ice is also an important factor, with realistic thickness sea ices exhibiting similar results, albeit with a weaker albedo response for multi-year sea ice to 75.3 %, first-year sea ice to 66.7 %, and melting sea ice to 35.7 %. The type of oil also plays a significant role on the response of sea ice albedo, with a relatively opaque and heavy crude oil (Romashkino oil) causing a significantly larger decrease in sea ice albedo than a relatively transparent light crude oil (Petrobaltic oil). The size of the oil droplets polluting the oil also plays a minor role in the albedo response, with weathered submicron droplets (0.05–0.5 µm radius) of Romashkino oil being the most absorbing across the optical wavelengths considered. Therefore, the work presented here demonstrates that low background concentrations of small submicron to micron-sized oil droplets have a significant effect on sea ice albedo. All three types of sea ice are affected, however first-year sea ice and particularly melting sea ice are very sensitive to oil pollution; thus, the Arctic may become more vulnerable to oil pollution as the ice becomes progressively thinner and younger in response to a changing climate.
