N2 - Network models are used in this work to study the behavior of a piping system with a side branch. Linear and nonlinear models of the sound production in the shear layer of a T-joint, which are obtained numerically, are integrated in the network model. A three-dimensional finite element computation is carried out to characterize the acoustic impedance of an additional element of the network. This combination of numerical techniques provides an approach to study the stability and limit-cycle amplitude of a piping system.
