Abstract

This paper presents a new technique permitting the determination characteristic impedance of viscoelastic conduits filled with viscous fluid. The method assumes only the measurement of pressure and flow at one location. To test the accuracy of this technique the characteristic impedance was calculated in a computer model of a single vessel having various terminal impedances and various lengths where the characteristic impedance was known a priori. The comparison of results obtained by the new technique and the classical one shows that both methods provide values of characteristic impedance similar to the true ones in reflection-less system. However, variation of terminal impedance and vessel length affects only the accuracy of the classical method. The values of characteristic impedance computed by the new technique remains identical to the true ones for all terminal examined impedances and lengths.
