Gas flow through interconnected ducts and pipelines of varying lengths and cross-sectional areas is considered. The distributed-lumped parameter model proposed by Whalley (1) has been extended to include the analytical determination of the responses of intermediate variables. To illustrate the procedure, a general two-stage distributed-lumped parameter model which is used to predict flow patterns following an input change is employed. Two specific applications are examined and simulated flow transient response records arising from pressure variations are presented.
