摘要:      建立3D的CFD模型,对埋管下部泄漏油品在孔隙度为0.45的紧凑土壤区域及孔隙度为0.47的疏松土壤中的扩散进行了模拟分析。结果表明:在紧凑土壤中,油品以圆滑的椭圆形向四周扩张,扩散宽度、深度和面积在泄漏初期增幅较大,扩散一段时间后增幅均变小,扩散区域的体积随时间以较小的增长率增长;在疏松土壤中,油品以上窄下宽的扩散区域向下延伸扩张,扩散宽度和面积的增长趋势均是先快后慢,而扩散深度的增长率明显大于在紧凑土壤中的增长率,扩散区域的体积随时间以较大的增长率稳步增长

Abstract: A 3D CFD model was established. The oil diffusion of lower leakage of the pipe in the soil porosity of 0.45 and 0.47 was simulated and analyzed. The results show that the oil spread to the surrounding area to expand in a way of oval in compact soil. The area, width and depth of spread increase largely in the initial of the leakage. After diffusion several minutes, they are increasing stably over time and the volume of diffusion is in smaller growth rate as the time changed. The oil spread downward expansion over narrow width of the diffusion region in loose soil. Spread width and area growth trends are slow down after. The depth of spread increased larger than former soil and the volume of diffusion were in larger growth rate as the time changed.

Key words: Oil pipeline ,  Spread range , Diffusion , Simulation
