“…However, for the study of pumps like external gear ones, even if the 2D modeling approaches give interesting results, they cannot predict the internal flow behavior like 3D models [9,10]. This depends on the fact that during the operation of an external gear pump, the flow is really complex because of the rotation speeds (typically in the range 500-3000 rpm) and high pressure.…”

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. Starting from a geometry of the pump, a three-dimensional computational fluid dynamics (CFD) model has been built up using the commercial code PumpLinx ® . All leakages have been taken into account in order to estimate the volumetric efficiency of the pump. Then the pump has been tested on a test bench of Casappa S.p.A. Model results like the volumetric efficiency, absorbed torque, and outlet pressure ripple have been compared with the experimental data. The model has demonstrated the ability to predict with good accuracy the performance of the real pump. The CFD model has been also used to evaluate the effect on the pump performance of clearances in the meshing area. With the validated model the pressure inside the chambers of both driving and driven gears have been studied underlining cavitation in meshing fluid volume of the pump. For this reason, the model has been implemented in order to predict the cavitation phenomena. The analysis has allowed the detection of cavitating areas, especially at high rotation speeds and delivery pressure. Isosurfaces of the fluid volume have been colored as a function of the total gas fraction to underline where the cavitation occurs.

Abstract-Aiming at the characteristics of the course of Fluid Machinery and the weakness of the traditional teaching, CFD technique was introduced into classroom teaching and the fluid components were simulated by applying the CFD software. CFD technique can record and reconstruct the whole flow information of the fluid components, and may realize visualization in virtual reality really. The application of CFD technique can not only arouse the students' interests and build up sensibility cognition of students, make the teaching change from theoretical and principle mode to liberal and application mode, but also help students to understand and master the design of the internal construction of fluid components and the meanings of the parameters. Finally, this application realizes the expansion of teaching content and results in an elevation of teaching quality.
