Method for Lumped Parameter simulation of Digital Displacement pumps/motors based on CFD Daniel B.
In this paper, the focus is therefore on development of a method for lumped parameter simulation using CFD to determine model parameters by which the CFD accuracy is implemented in the lumped parameter model.
The computationally expensive steady CFD simulations may then be conducted once for a given DD geometry, and subsequent transient simulations be conducted with low computational cost.
Figure 8 shows a comparison between the LPM and the transient CFD model simulation.
This lumped parameter model has shown to exhibit similar dynamic response as a computationally expensive transient CFD model, while a simulation may be performed in less than one minute compared to several days for the transient CFD.
