三維數(shù)值波浪水槽的構(gòu)建及圍油欄結(jié)構(gòu)水動(dòng)力學(xué)性能的研究
[Abstract]:In recent decades, with the rapid development of China's national economy, the ocean plays a very important role in the development of the national economy. Oil spill accidents occur from time to time, and the containment column is an important equipment to prevent oil spill from spreading. Therefore, it is of great significance to study the performance of the oil enclosure under various sea conditions. In this paper, 3D numerical wave flume is successfully constructed based on Flow3D software. The wave is generated by boundary condition in 3D flume, and wave elimination is realized by sloping porous media structure in 3D wave tank. The wave flume constructed by Flow3D is based on the finite difference method, using the FAVOR technique to display the geometry, and also using the RNG 魏-蔚 model and the VOF method. Then the wave force extracted from Flow3D is input into the ANSYS finite element software, and the stress analysis of the oil column structure is carried out in ANSYS. In this paper, FLOW3D is used to simulate the linear regular wave, which can generate the stable wave field for a long time, and calculate the influence of different slope and different porosity on the wave dissipation performance of different material particle size. The mechanical properties of floating oil column structure are analyzed in ANSYS, and a series of suggestions are put forward.
