Abstract
Gear pumps represent the majority of the fixed displacement machines used for flow generation in fluid power systems. The internal conformation of this system contains many undetermined variables, due to both the manufacturing techniques and the breaking-in pressure, that strongly affect the pump performance. The 3D CFD model of this type of products is particularly difficult to develop and is presented in this work, which main purpose is a sensitivity analysis on key operating parameters of a gear pump studied with both numerical and experimental techniques.File in questo prodotto:
