Simulation of leakage flow through dynamic sealing gaps in hydraulic percussion units using a co-simulation approach
Håkan Andersson,L.J. Holmberg,Kjell Simonsson,D. Hilding,M. Schill,T. Borrvall,E. Sigfridsson,Daniel Leidermark +7 more
TL;DR: In this paper, a co-simulation method was developed to also simulate the dynamic behavior of sealing gap regions in hydraulic percussion units, based on a 1D system model representing the fluid components and a 3D finite element model representing structural parts of a hydraulic hammer.

A complete analysis of axial piston pump leakage and output flow ripples
TL;DR: In this article, the authors focused on understanding the flow losses and the resulting flow/pressure dynamics in a piston pump, and presented equations to evaluate leakages in all piston pump gaps and tested against numerical models to determine the general pressure/flow pump dynamic characteristics.

The effect of piston grooves performance in an axial piston pumps via CFD analysis
Sushil Kumar,Joseph M. Bergada +1 more
TL;DR: A finite volume based Reynolds equation model has been formulated for the piston-cylinder clearance which considers the piston eccentricity and the relative tangential movement between piston and barrel as mentioned in this paper, and different grooves configurations have been evaluated in search of finding minimum leakage, minimum appearance of cavitation and maximum restoring torque.
