Wave front dispersion due to fluid-structure interaction in long liquid-filled pipelines
Half a century ago Richard Skalak (1923-1997) (Ref 1) published a paper with the title "An extension of the theory of water hammer" (Refs 2, 3, 4), which has been the basis of much subsequent work on hydraulic transients with fluid-structure interaction. The paper considers the propagation of pressure waves in liquid-filled pipes and the coupled radial/axial response of the pipe walls. In a tri...
متن کاملTime-frequency Analysis of Acoustic Signals for Condition Monitoring of Fluid-filled Pipelines
In this paper, a wave propagation model is developed to investigate the wave propagation in fluid-filled steel pipe. Based on the Kennard shell equations the investigation is achieved under the conditions of coupling between the shell elastic acoustic field and the interior fluid acoustic field. Tests are conducted on fluid-filled pipeline blockage detection. An active acoustic source is used t...
متن کاملNoise Control for Fluid Power Systems
Pressure pulsation, created by the operation of hydraulic pumps in a fluid power system, is one of the primary causes of noise issues from hydraulic machinery. The wave energy resulting from such pulsation propagates in both the wall and the fluid of the flow pipes associated with the fluid power systems, inducing fluid borne vibration of the pipes and the consequent noise radiated from the pip...
متن کاملNoise Generation in Household Refrigerators: An Experimental Study on fluid Borne Noise
The oscillatory pressure disturbance created by the refrigerant flow through pipes and components is one of the main sources of noise in household refrigerators. This type of excitation is transferred to the pipes and the vibratory energy travels through the structure reaching the cabinet from which it radiates as sound energy. In order to obtain a better understanding of this type of noise a h...
