IMPROVEMENT OF FLUID PIPE
LUMPED PARAMETER MODEL*
Abstract:
The traditional lumped parameter model of fluid pipe is introduced and its drawbacks are pointed out. Furthermore, two suggestions are put forward to remove these drawbacks. Firstly, the structure of equivalent circuit is modified, and then the evaluation of equivalent fluid resistance is change to take the frequency-dependent friction into account. Both simulation and experiment prove that this model is precise to characterize the dynamic behaviors of fluid in pipe.
