This paper presents an experimental study of the acoustical effects of cavitation caused by a
water flow through an orifice. A circular-centered single-hole orifice and a multi-hole orifice …

Pressure pulsations and mechanical vibrations in pipe systems may cause excessive noise
and may even lead to damage of piping or machinery. The excitation mechanism can be …

The hydraulics of perforated plates has a large impact on the design of water systems;
particularly, estimating the inception of cavitation is fundamental for correctly assessing the …

Experimental setup with a submerged cavitating jet has been used for the study of
influences of material, exposure time and working fluid temperature on the erosion process …

New experiments have been carried out on the generic case of the flow through orifice
plates. The aim has been to validate empirical correlations used for the prediction of …

Liquid flow facilities are usually categorized as towing tanks, seakeeping and maneuvering
basins, circulating water channels, blowdown facilities, and water tunnels. A very complete …

Increasing cavitation in a flowing liquid in a pipe system is associated with increasing levels
of sound or noise and vibrations. It can lead to large loads if steam bubbles implode close to …

A novel approach for the regression on passive acoustic emission spectra is presented.
Acoustic emission of the fluid flow through an orifice plate is partly characterized by …

This paper presents a prediction technique to determine the pressure ripple in the fluid and
the vibration levels in the pipe due to cavitation from an orifice plate. Currently, there is no …

Prediction of chemical composition from passive acoustic measurements using multivariate
regression (ie acoustic chemometrics) from liquid flows has been reported as a promising on …
