摘要

旋转体的边界积分方程有一个格林函数核，它可以写成自由空间格林函数的方位积分。我们证明了现有的计算该积分的近似方法存在效率或稳定性问题。其中一种方法的改进可以在保持效率的同时控制精度。

Numerical kernel construction for bodies of revolution with highorder Fourier modes

Boundary integral equations for bodies of revolution have a Green's function kernel that can be written as the azimuthal integral over the free-space Green's function. We show that existing approximation methods for computing this integral suffer from efficiency or stability problems. Improvement of one of these methods leads to controllable accuracy while retaining efficiency.
