Abstract

Regular operation, pre-repair and repair work on tanks, as well as outflows of oil products and other flammable liquids under the influence of seismic loads, fires and explosions on tanks are the source of technogenic impact on the environment. Therefore, the influence treatment of the fluctuations and vibrations on the storage tanks for environmentally hazardous liquids and the assessment of reducing the load on nature is a very relevant scientific and practical issue to improve the environmental safety of areas adjacent to the tanks. This paper treats free and forced liquid vibrations in prismatic tanks filled with an incompressible ideal liquid. The developed method allows us to estimate the level of the free surface elevation in prismatic tanks under suddenly enclosed loadings. The proposed method makes it possible to determine a suitable place with a proper height for installation of the baffles in tanks by using numerical simulation and thus shortening the expensive field experiments. The proposed approach could be applied to various environmentally hazardous liquids. This will increase the environmental safety level of the territories adjacent to stationary tanks with environmentally hazardous liquid. It will also be possible to prevent emergencies.
