Abstract: The conventional transfer matrix models of fluid elements are modified to meet modeling of complex fluid networks. A convenient method of dealing with junction boundary conditions is introduced, and an efficient approach to dynamic modeling and simulation of large-scale fluid networks with multiple inputs and terminations is proposed. Based on h(t)=F-1[H(jw)],by transforming inverse fourier transform into fourier transform, into fourier transform, the fast fourier (FFT) algorithm is applied to dynamic simulation of akrge-scale fluid networks in time domain. The calculation results are good agreement with experiments.
