Using the Activity Index - Examples > Example 2: the 3 piston pump (case study)
Validation of the final reduced model
Models were compared with the observation of displacements of moving parts, the shape of flow-rate delivered at the outlet of the pump, and pressure in one piston chamber.
Figure 52: Results of the complex model compared with reduced model
Figure 53: Comparison of the output flow rate
An excellent agreement of the results was observed. Shapes of curves were similar, all frequential components were preserved.
