Wave Propagation and Reflection in Systems of Compliant
N. N. Kizilova
V. N. Karazin Kharkiv National University, Ukraine
ABSTRACT
Axisymmetric wave motion of a viscous incompressible liquid in a system, which is consisted of a long thin elastic tube and a terminal element with a complex admittance is investigated. Expression for the input admittance of the system taking into account wave reflection at the end of the tube is obtained. The dependence of the input admittance on geometrical and mechanical parameters of the system is investigated. The equation for calculation the socalled resonant harmonics where the input admittance reaches its extreme is obtained. The harmonics is considered as resonant, when any alteration in terminal admittance causes a significant variation in its amplitude. The influence of variations of the model parameters on the amplitude and the phase of the input admittance is closely investigated. Possible applications of the proposed model for biomechanical interpretation of novel methods of medical pulse diagnosis are discussed.
