Abstract

This study develops a two-dimensional time-domain boundary element method to address the acoustic coupling in vortex-sound interaction phenomena, specifically for geometries with impedance boundary conditions. To ensure compatibility with the two-dimensional time-domain boundary integral equation, time and spatial basis functions were used to discretize the improved time-domain admittance boundary condition. The proposed method was validated through the construction of characteristic matrices and numerical results from several typical cases. It demonstrates high accuracy in both internal and external scattering problems, making it well-suited for studies on acoustic coupling.

非定常声耦合问题的阻抗边界条件二维时域边界元法
本研究开发了一种二维时域边界元方法,以解决涡流与声音相互作用现象中的声耦合问题,特别是针对具有阻抗边界条件的几何结构。为确保与二维时域边界积分方程的兼容性,使用了时间和空间基函数来离散改进的时域导纳边界条件。通过构建特征矩阵和几个典型案例的数值结果,对所提出的方法进行了验证。该方法在内部和外部散射问题上都表现出很高的准确性,因此非常适合声耦合研究。

期刊介绍: This journal is specifically dedicated to the dissemination of the latest developments of new engineering analysis techniques using boundary elements and other mesh reduction methods. Boundary element (BEM) and mesh reduction methods (MRM) are very active areas of research with the techniques being applied to solve increasingly complex problems. The journal stresses the importance of these applications as well as their computational aspects, reliability and robustness. The main criteria for publication will be the originality of the work being reported, its potential usefulness and applications of the methods to new fields. In addition to regular issues, the journal publishes a series of special issues dealing with specific areas of current research. The journal has, for many years, provided a channel of communication between academics and industrial researchers working in mesh reduction methods Fields Covered: • Boundary Element Methods (BEM) • Mesh Reduction Methods (MRM) • Meshless Methods • Integral Equations • Applications of BEM/MRM in Engineering • Numerical Methods related to BEM/MRM • Computational Techniques • Combination of Different Methods • Advanced Formulations.
