Sound Radiation from an Open End of the Wedge-Shaped Waveguide. I. Method of Solution and Numerical Algorithm
RESUMO
The 2D boundary problem arising in the study and analysis of characteristics of sound field radiated from the open end of the wedge-shaped waveguide is presented in the paper. The characteristic feature of the wave-guide geometry is that the end points of the boundary planes are situated on different distances from the top of the wedge. Major attention in this first part of the paper is focused on considering analytic structure of the wave fields and the principal features of solving algorithm. It is shown, that for the considered problems there is an indeterminacy in the form of analytical solution. By doing the analysis of numerical results the indeterminacy can be removed taking into account the minimizing volume of computations involved at their given accuracy.
