海洋管线涡激振动流体力数据查询研究
|
摘要
在进行管线涡激振动快速预测程序或软件开发时,流体力查询匹配问题尤为关键。计算流体力数据的获取需要经过试验或CFD计算,过程十分繁琐和耗时,导致流体力数据的分布难以做到规则和全面。为此文中针对流体力杂乱特点,研究了流体力数据查询插值算法和程序,为海洋管线涡激振动预测软件提供基础。论文实现了反距离加权法的邻域插值算法和三角形插值算法,以及补全数据后的规则数据下的双线性插值算法,并通过算例对各种算法进行了评估,为海洋立管涡激振动快速预测软件开发提供基础。
In the development of the rapid-prediction program or software for the pipeline-based vortex-induced vibration,the query matching for fluid force is critical. The data on fluid force requires test or CFD calculation. The process is very tedious and time-consuming, which makes the data distribution irregular and incomprehensive. This article focuses on the chaotic characteristics of fluid force, and explores the interpolation algorithm and program for fluid-force data query, thus providing basis for the development of the prediction software for vortex-induced vibration in the marine pipeline. The following algorithms are worked out:the neighborhood interpolation algorithm and the triangle interpolation algorithm based on the inverse-distance weight, as well as the bilinear interpolation algorithm targeted at the ruling data and based on the data completion. Various algorithms are evaluated through the calculation examples. These lay a solid foundation for the development of the rapid-prediction software for the vortex-induced vibration in the marine pipeline.
