| Реферат: | eng: The flow turbulence impact on the formation of erosion areas near gravity type oil platforms is studied. The SST (shear-stress transport) turbulence model describing large-scale structures in the internal area and small-scale turbulence in the external area is used for computing turbulent fluid flow. The model grounded on estimation of turbulent behavior of the fluid flow in the bottom flow region where the soil particles transfer is influenced by fluid flow and sea-bed irregularities is applied for estimation of soil erosion. Three sets of numerical studies referred to increase of hydrodynamic values and flow turbulent transition are given. |
