摘要
结合商用软件Fluent 14.5自定义函数(UDF)功能,采用速度边界造波法和阻尼消波技术,通过流体体积函数(Volume of Fluid,VOF)追踪自由液面,建立波浪、波流数值水池。采用双向耦合分离法思想,借助Workbench 14.5流固耦合模块System Coupling将流域和结构域计算数据交互传递,在数值波浪、波流水池中对长径比为8的柔性立管进行双向流固耦合模拟,分析其载荷响应,得出波浪场中不同流速下受力点的变化情况及不同波流方向下振动平衡状态的变化情况。
Numerical wave/wave-current tanks with high effectiveness in wave-making and wave-absorbing functions are established on the platform of Fluent 14.5 with UDF programs by using velocity boundary and damping wave technique as well as VOF method. With the two-way coupling separation concept, transferring the data of the fluid domain and structure domain in the module System Coupling of the Workbench 14.5, the motion response of a flexible riser with the aspect ratio of 8 is simulated in the numerical tank, and the loads and response on the riser are analyzed.
