Abstract
A method of estimating wave speed in a pipe was proposed by the authors. The estimation process is thought to be influenced by the nature of transient phenomenon in a pipe, the optimized finite element model used as a pipeline dynamics model, and the identification algorithms Major factors that may influence the estimation process are investigated, such as valve operating time, pressure noise caused by quick valve operation, the relationship between the number of elements of the pipeline model, a sampling time and regression gain of identification algorithms. The effects of the major factors are illustrated through experimental study.
