|
摘要
为实现海底输气管道泄漏扩散结果的实时可视化仿真,对海底输气管道泄漏扩散可视化仿真软件进行了结构分析与功能模块划分,以数值模拟实验为基础建立了海底输气管道泄漏扩散模型数据库,编写Matlab程序读取数据库信息并进行简化处理,生成了泄漏气体扩散影响范围数据点矩阵。使用统计学方法,并引入边界曲线拟合系数对泄漏影响范围边界进行曲线拟合,实现了对泄漏气体影响范围的实时判断。在此基础上,使用Matlab/C++混合编程方法,完成了海底输气管道泄漏扩散可视化仿真软件设计及开发。
In order to realize the real-time visualized simulation of submarine gas pipeline leakage diffusion,The framework structure and functional modules of visual simulation software for leakage diffusion of submarine gas pipeline are analyzed,the database of submarine gas pipeline leakage diffusion model is established on the basis of numerical simulation. The database files are read by the MATLAB programand simplified to generate the data point matrix of leakage gas diffusion range. By introducing boundary curve fitting coefficient,the boundary curve of leakage influence range is fitted using statistical method,and the real-time judgment of the leakage gas influence range is realized. On this basis,the visual simulation software of submarine gas pipeline leakage diffusion is developed by using MATLAB/C + + hybrid programming method.
