剪切流作用下超大型浮体的非线性水弹性响应

本文研究了在剪切流和深水行进波的共同作用下超大型海洋浮体(VLFS)的非线性水弹性响应问题。针对垂向速度呈指数分布的有旋剪切流情形,提出引入流函数构建物理模型的方法,并运用不依赖于任何物理小参数的同伦分析方法(HAM)求得收敛的近似解析解。最后利用计算结果详细讨论了几种重要物理量对板的非线性水弹性响应的影响,我们发现指数剪切流与行进波同向时,涡量越大板的波形 …

超大型浮体在波流相互作用下的非线性水弹性响应

本文解析研究了在均匀流作用下漂浮在流体表面的无限长薄板的非线性水弹性响应。在势流理论框架下,假设流体是无粘的、不可压缩的,运动是无旋的。我们以拉普拉斯方程为控制方程,在板-波-流共同场中构建非线性动力学和运动学边界条件。借助同伦分析方法求得速度势、板挠度的收敛近似解析解;并深入考查了一些重要物理量对非线性水弹动力特性的影响。其中发现薄板的非线性水弹性响应依赖 …
