Solving Acoustic Radiation and Scattering based on Coiflet
In this paper,the acoustic Helmholtz boundary integral equation is solved using Coiflet scaling functions with interpolation approximation property.The scaling functions are utilized as base and test functions in Galerkin method and the expanded coefficients are the values of the function in sampling points,so the number of numerical integral is reduced.Two numerical examples are given and the calculation results agree well with the theoretical results,which show the high accuracy of the estimation and demonstrate validity and applicability of the method.
