Abstract
The transmission line method (TLM) is a very efficient method for dynamic modelling of flow in pipelines, and uses delay elements to represent wave propagation. In this paper an existing TLM model is investigated and shown to have some deficiencies. Some adjustments are proposed to avoid these deficiencies and enhance the transient and steady state accuracy. Very good agreement is obtained between this adjusted TLM and an analytical model. The model has been implemented in simulation of a number of highly dynamic systems, and has been found to be robust and reliable.
