The Transient Response of Fluid Lines

Abstract

Functional operators are derived for the propagation factor and characteristic impedance for small amplitude waves in rigid uniform fluid transmission lines when the effects of varying velocity profile and heat transfer are included. The special case of sinusoidal excitation yields the identical result given by Iberall. The results, however, are used particularly to determine the impulse and step responses of a line, which clearly demonstrate the observed dispersion of fast transients.
