A study on the internal fluid dynamic of a high-pressure external gear pump is described in
this paper. The pump has been analyzed with both numerical and experimental techniques …

Small and micro hydropower systems represent an attractive solution for generating
electricity at low cost and with low environmental impact. The pump-as-turbine (PAT) …

Pressure ripple has always been a major drawback in hydraulic circuits, since it is the main
source of the overall noise emitted by the pump. This article presents a theoretical analysis …

In positive displacement pumps, the main volumetric loss at high speed is due to the
incomplete filling of the variable volume chambers. The prediction of the limit speed and of …

This paper compared the capabilities of the artificial neural network (ANN) and the fuzzy
logic (FL) approaches for recognizing and discriminating partial discharge (PD) fault …

Advancements related to the correlation between pump design parameters and the
kinematic flow ripple in balanced vane pumps are addressed in the present work. In …

The present study proposes an analytical methodology to estimate the variable loads
applied to the vanes of balanced vane pumps. The dissertation is adopted to detail the …

A full 3D unsteady numerical model with dynamic meshes is developed to simulate the fluid–
structure interaction in the non-returning valves of air-operated diaphragm volumetric …

This research presents a comparison between two numerical approaches developed and
later compared for studying External Gear Pumps (EGPs). Models have been developed for …

In the last years Prognostic and Health Management (PHM) has become one of the
challenging topic in the engineering field. In particular, model-based approach for diagnostic …
