This paper presents a method of computing pressure pulsations in complicated pipelines by using the topological network analysis which is an analytical method for electrical circuits. The pressure and flow amplitudes in each one-dimensional pipeline is computed by using the transfer matrix method. The one-dimensional pipelines are replaced by the two-port circuits with three admittances which are calculated from the transfer matrices. The whole pipeline is replaced by the equivalent circuit to be composed of the two-port circuits. The pressure amplitudes at the nodes are computed by using the topological network analysis. The computations are repeated for all the sinusoidal components contained in the input flow. The magnitudes of the pressure pulsations are obtained together with all the pressure amplitudes. The computed results for several model pipelines were in good agreement with experimental ones.
