摘要
给出了求解二维空穴声辐射问题的一种数值方法.该方法用单层位势逼近外场声压,再利用位势理论的跳跃关系将问题转化为第二类边界积分方程组的求解问题,然后利用Nystrm方法求解.通过求得的数值解与解析解的对比,证明文中给出的数值模型有较高的精度.
In this paper, a numerical method of the solution to acoustic radiation problems of 2-D cavity is analyzed. This method uses single-layer potential to approach to exterior sound pressure, then turns it to the solution to the second kind boundary integral equations by jump relations of the potential theory, and then solves it with method. Numerical examples illustrate the accuracy of the method.
