Experimental and Numerical Characterization of External Gear Pumps (EGPs)

Development and validation of lumped-parameter (0D) and 3D CFD models, combined with experimental testing, for the analysis and optimization of External Gear Pump performance.

Main research topics include:

1. Pump Efficiency.  Investigation of tribological phenomena and volumetric losses to assess their impact on overall pump efficiency and performance.
2. Run-in Cycle Optimization.  Analysis and optimization of the run-in process, focusing on cycle time reduction and improvement of pump performance.
3. Self-Priming of Multiple EGPs.  Development of 3D CFD models in Simerics-MP+ to investigate and predict the self-priming behavior of multiple External Gear Pumps.
4. Noise Emissions.  Experimental characterization and analysis of pump noise emissions under different operating conditions.
