Abstract

Abstract: In this paper a three-dimensional CFD methodology to improve the performance of hydraulic components is shown. The study regardsresearch activities developed during the last two year by the Hydraulic Research Group of the University of Naples Federico II coordinated by the Prof. Adolfo Senatore. Models were build up with PumpLinx ®, a commercial CFD 3D code developed by Simerics Inc. ®, that solves numerically the fundamental conservation equations of mass, momentum and energy and includes accurate physical models for turbulence and cavitation. The paper demonstrate that this methodology may produce a significant improvement of the performance of several different components with an important costs reduction for prototyping phase. The paper presents results obtained on variable displacement vane pump and on a vane pump power split transmission, both pumps are used for mobile application. Analyzing the results of this paper it is possible to appreciate the transversality of the adopted methodology. The first analysis is made to avoid cavitation phenomena. The study has regarded the analysis of the forces acting on the pump ring related due by cavitation. The second study has regarded a new vane pump power split transmission concept developed by a research collaboration between the University of Naples and the University of Minnesota (USA). The goal of this activity is the investigation of the output power of the transmission. Results will be compared with experimental data by the end of 2015 when the prototype will be available. The flexibility the presented methodology makes this approach very interesting in the Hydraulic field offering the opportunity of solve completely different issues in many applications.
