Minimizing Pressure Pulsations in a Centrifugal Compressor
Volume 6: Structures and Dynamics, Parts A and B, 2011As a centrifugal impeller rotates, it converts shaft mechanical power into fluid power - static and dynamic pressure. As a result of this aerodynamic process, the flow in the compressor has steady and unsteady components. The latter is undesirable as it can manifest itself as pressure pulsations that consequently cause machine vibration, noise and ...

Attenuation of low frequency pressure pulsations
2022In this thesis, the concept of hydraulic pulsating filter is explored and developed. The filter or resonator is designed to attenuate the pulsation that occurs when the hydraulic pump is discharged. Pumps pulsate over a range of frequencies, depending on pump design, speed, displacement, and other factors.

Transducers for measuring strong pressure pulsations
Measurement Techniques, 1997Results are presented from an experimental study of pressure pulsations inside the precumbustion chamber of a model of a combustion engine. The pulsations are studied with the use of thin-film capacitive transducers.

A pressure control switch with a pulsation filter
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1957THIS PAPER describes a pressure control switch which uses viscous damping to prevent the transmission of pressure pulsations from a pump outlet system to the pressure control system. This was accomplished by designing a pressure switch which has certain dynamic characteristics as well as the normal static characteristics.

THE PRESSURE PULSATION OF 11 APRIL 1944
Journal of Meteorology, 1949Abstract Windstorms of 11 April 1944 were associated with the eastward movement of a large pulsation in pressure and strong easterly surface winds. Barograph and wind records from many stations are used to show the hourly movement of this pulsation.
