15 1D Simulation Model The 1D pump flow model is discretized into many volumes comprised of pipes and flow splits (volumes), and pipe passages are further discretized into sub volumes. The 1D Navier-Stokes equations, namely conservation of mass, momentum and energy are solved every time step in every sub volume. Conservation of species is also considered to solve for species transport throughout the system. In the figure, the flow volumes used in the model are shown by alternating colors. Both the inlet and outlet ports are divided into three sections for more accurate wave propagation through the port. Discretization of flow passages in the 1D model

16 1D Simulation Model 16 Since the pump has 10 outer teeth, there are 10 chamber volumes, and one cycle of the pump is represented as one revolution of the outer gear. The flow path from the oil pan to the chamber volumes is highlighted in blue, while the flow path from the chambers to the outlet is highlighted in red. The leakage path between chambers is highlighted in green. The changing volume in each "Vol1", Vol2", etc part pulls the oil from the pan into each chamber as its volume expands. Then when the volume in each chamber compresses, the oil is forced to the outlet side of the pump. The internal leakage between each chamber is modeled with parts "gap1", "gap2", etc

17 1D Simulation Model Three internal leakage paths are used in the model. The dominant path is highlighted green (leakage between teeth), the two minor paths are highlighted orange and pink.

18 1D Simulation Model The 1D model was built directly from the CAD model of the pump using the GEM3D preprocessor of GT-SUITE.

19 1D Simulation Model There are three distinct sections for both the inlet and outlet ports, to represent the flow area between the pumping chambers and these port sections. The model has 133 total flow volumes, 110 of which are pipe sub-volumes

20 1D Simulation Model Free/dissolved gas is included in the model, based on Henry s Law A time constant is used to control the rate at which air goes from dissolved free state and vice versa The amount of gas that can be dissolved in a liquid at steady state is proportional to the pressure and dependent on the Bunsen coefficient, B The Bunsen coefficient for oil/air mixtures is on the order of V gas d, ss (1bar,273 K ) BVliq P Patm Gas dissolved The model assumes no free air at the oil pickup tube inlet, but 100% dissolved air in the oil B Pressure E.

21 Results Comparison between model results and experimental data with a Toil of 800C and a suction tube orifice diameter of 15mm

22 Results Comparison with different suction tube orifice diameters, while holding outlet pressure at 3 bar and 800C NO CAV MASS FLOW-RATE CAV pout = 3 bar

23 Results Comparison with different suction tube orifice diameters, while holding outlet pressure at 3 bar and 800C SUCTION PRESSURE pout = 3 bar

24 Results 3000rpm TOIL=80 C PDELIVERY [bar] PDELIVERY [bar] 3000rpm TOIL=80 C Angle [deg] NO CAV Angle [deg] CAV

25 Results Pressure pulsation comparison at 3000 RPM and 800C 15mm NO CAV 5mm CAV

26 Results Influence of oil type and suction tube diameter on pump mass flow Toil = 200C Toil = 800C

27 Conclusions A numerical and experimental investigation on the cavitation in a gerotor oil pump has been done. The pump has been forced to cavitate varying the suction pressure. An experimental investigation has been performed by the University of Naples Federico II on a hydraulic test bench.

28 Conclusions The Pump performance in no-cavitating and cavitating conditions has been measured; these data have been used to compare to the 1D simulation model. The comparison between the model results and experimental data has shown a good accuracy with a maximum gap of 7%. The model has demonstrated to correctly predict cavitation

29 Work in Progress The model is able able to predict the power request of the pump Study of other Getoror pumps

30 Work in Progress Gerotor pump cavitation Fault Diagnosis Study of other pumps like the vane pumps and the piston pumps
