摘要
针对充流管道单向流固耦合数值模拟过程复杂、数据在耦合传递中存在偏差的问题,采用C++语言编制了充流管道单向流固耦合数值模拟程序,实现了从模型建立、流体计算到结构分析过程的自动化,确保了从流体计算到结构计算过程中数据传递的准确性.利用参考文献中的试验数据验证了此程序计算结果的正确性,以实际发电厂的一段疏水管道为例进行单向流固耦合数值模拟,描述了程序自动建立管道模型、模拟管内流体压力分布以及将流体压力数据导入管道结构中进行管道应力计算的过程.结果表明:该充流管道单向流固耦合数值模拟程序具有结果准确、操作简便的特点,可应用于多种充流管道的设计改造和风险预测中.
According to the fact that the process of numerical simulation on oneway fluid-structure interac- tion of fluid-filled pipeline is complex, and the data transferred in calculation is not exact, a simulation pro- gram has been compiled using C＋ q- language to automatically implement the model building, fluid calcu- lation and structure analysis, with which the automation of numerical simulation on one-way fluid-struc- ture interaction of fluid-filled pipeline is realized, and the authenticity of the data transferring is ensured. The calculation results of this program are verified by relevant experimental data in references. Taking the drain pipeline in a power plant as an ob}ect of study, numerical simulation is performed on the one-way flu- id-structure interaction, including automatically building the pipeline model, simulating the pressure distri bution of fluid inside the pipeline and analyzing the stress in the pipeline by introducing fluid pressure data to the calculation. Calculation results show that the program previously compiled is accurate in calculation and facile in operation, which is therefore suitable for design, retrofit and risk prediction of fluid filled pipeline.
