| Abstract(in English) | An acoustic analysis using the finite element analysis is difficult for the acoustic tube with some branches. In this paper we propose an equivalent model of the tube with the wall impedance which is computed from the input impedance of the branch tube, and discuss efficient algorithms for composing element meshes or integration of the spectral element method. The result of numerical simulation is shown for the acoustic tube model. |
