提出了一种新的流-结构相互作用方法，该方法将尖锐界面浸没边界法(IBM)流动求解器与基于有限元方法(FE)的固体动力学求解器相结合。耦合方法为复杂的流固耦合问题提供了稳健和高保真的解，例如涉及三维流动和粘弹性固体的问题。FSI解算器用于模拟发声过程中声带的流动诱发振动。对二维和三维模型进行了检验，并与已确定的结果进行了定性和定量比较，以验证求解器的有效性。该解算器被用来研究二维喉部模型中发声的开始和三维模型中声门射流的动力学，并给出了这些研究的结果。
A new flow-structure interaction method is presented which couples a sharp-interface immersed boundary method (IBM) flow solver with a finite element method (FEM) based solid dynamics solver. The coupled method provides robust and high fidelity solution for complex fluid-structure interaction (FSI) problems, such as those involving three-dimensional flow and viscoelastic solids. The FSI solver is used to simulate flow-induced vibrations of the vocal folds during phonation. Both two- and three-dimensional models have been examined and qualitative as well as quantitative comparisons made with established results in order to validate the solver. The solver is use to study the onset of phonation in a two-dimensional laryngeal model and the dynamics of the glottal jet in a three-dimensional model and results from these studies are also presented.
