|Abstract:||A technique named the RDT (Reproduction of Diagonal Terms) is presented to improve the accuracy and the reliability of Conventional Boundary Integral Equation (CBIE) applied to acoustic radiation from axisymmetric bodies. In CBIE, the higher order singular integral is eliminated by placing a fabricated point source inside the boundary. Numerical results for a spherical structure show that the accuracy is obviously raised up to 10 times at higher frequency upon use of the RDT method, and the CHIEF and improved Burton & Miller methods can work with the technique presented in a wide frequency range with better accuracy.|
