| 摘 要： | 在应用油粒子法模拟溢油运动时,特征油粒子在体积和油膜粒子化方法上可以有多种选择,文章就不同特征体积的油粒子对溢油面积的影响进行了分析和比较,结果显示,溢油量相同时,特征油粒子的体积每减小一倍,溢油扩散面积增加14%-25%,减小10倍时,达到31%-43%.针对溢油扩散面积计算不足的情况,已有学者提出用"两阶段"法进行... |

| Abstract: | In the application of oil-particle method to simulate the oil spill,there are a lot of options for the size of characteristic oil-particle and the method of changing oil slick into particles.Effects by different sizes of characteristic oil-particle were analyzed and compared.Results showed that under the same total volume of oil spills,the simulated area of oil spill increased by 14%～25% as the size of the characteristic oil-particle decreased by 50% and simulated area of oil spill increased by 31%～43% as the size of the characteristic oil-particle decreased by 10 times.Two-stage method was proposed to improve the oil-particle method which has a shortage in calculating oil spill area,however,the two-stage method evenly distributed the changing oil slick into particles in space,while the oil film should be normal distributed in space.The method of changing oil slick into particles has been improved,and results show that the two methods are not much different in calculating the oil spill area,but the method improves the calculation of the slickness of oil film calculation according to the actual instance. |
