In this paper a general matrix formalism for predicting fluid-borne sound in gas filled pipe systems of arbitrary geometry is presented. Based on the formalism, a code, valid from the low frequency plane wave range up to frequencies where a large number of modes propagate in each pipe, has been developed. The formalism is based on representing the pipe system as an equivalent network of acoustical 2-ports, where each 2-port corresponds to a physical pipe element. Interfaces or branch points… CONTINUE READING
