Bond Graph Modeling and Validation of an Energy Regenerative System for Emulsion Pump Tests

Abstract EN

The test system for emulsion pump is facing serious challenges due to its huge energy consumption and waste nowadays.

To settle this energy issue, a novel energy regenerative system (ERS) for emulsion pump tests is briefly introduced at first.

Modeling such an ERS of multienergy domains needs a unified and systematic approach.

Bond graph modeling is well suited for this task.

The bond graph model of this ERS is developed by first considering the separate components before assembling them together and so is the state-space equation.

Both numerical simulation and experiments are carried out to validate the bond graph model of this ERS.

Moreover the simulation and experiments results show that this ERS not only satisfies the test requirements, but also could save at least 25% of energy consumption as compared to the original test system, demonstrating that it is a promising method of energy regeneration for emulsion pump tests.
