Název v původním jazyce

Hydrodynamic resonation through-flow system as acoustic circuit

Popis výsledku v původním jazyce

The paper proposes a derivation of general characteristic acoustic parameters of the hydrodynamic resonation system elements. The acoustic parameters of the system are the acoustic complianc and acoustic mass as primary parameters for calculation of thetheoretical resonation fundamental frequency for turbulent water-flow. Frequency model (5 kHz to 25 kHz) refers to the interpolation for the liquid pressure range from 5 MPa to 25 MPa. The analysis travels in a direction of a value comparison of concreteacoustic characteristic parameters for any element of the system and has been contrasted with theoretical conditions about an acoustic mass for tubes and an acoustic compliance for chambers. This system generates a modulate liquid jet as a result of resonanation chamber implantation. The theoretical model was built on the basis of knowledge of primarily geometric dimensions of the system and the pressures of the liquid to predict values of fundamental frequencies of oscillations.
