In the previous report, the concentrated mass model was proposed to analyze a nonlinear pressure wave phenomenon in a cylindrical straight tube. In this paper, we apply the model to a branch element. To confirm the validity of the proposed branch model, we perform experiments on a sound tube with a branch pipe, compare the experimental results with the numerical results. The numerical computational results agree very well with the experimental results. Therefore, it is concluded that the proposed branch model is valid for the numerical analysis of nonlinear pressure wave problem in a tube with a branch pipe.
