Wave dispersion is a key element in understanding the pulsating flows in a circular rigid pipe. This study suggests that an extended Taylor’s frozen field hypothesis should make the lumped parameter model be more practical because pressure instead of pressure gradient can be measured with simpler instrumentation. Lumped parameter model as well as wave dispersion is introduced, and then some experimental results with a blood flow simulator were analyzed to validate its idea.
