摘要
边界元法应用于计算流固耦合问题时,由于奇异积分的存在,会影响到计算结果的精度。本文描述了处理带有1/r 奇异积分和1/(r^2)二次奇异积分的处理方法,包括数学证明和数值积分方法,计算结果表明这种方法能提高精度。
While the Boundary Element Method(BEM) is adopted in computing the fluid-sol- id coupling.The existing singular integration may have an influence on the precision of the re- suit.The methods of treating singularities in as well as singularities in were presented,which include mathematical proof and numerical integration method.The calculating results show this method can improve the precision of the results.
