Numerical Modeling of Hydrodynamic Processes in the Gerotor Pump of the Lubrication System of Diesel Engines

Abstract

This article presents the results that serve as a methodological basis for creating a digital twin of a diesel engine lubrication system. At the first stage, mathematical and computer models have been created for the oil pump of the engine lubrication system. At the second stage, numerical modeling of hydrodynamic processes during pump operation has been carried out in order to verify and validate models based on experimental data. Next, a method of reverse engineering of pump performance characteristics is proposed, and its performance characteristic is constructed. Based on the calculations performed, recommendations have been developed to improve the accuracy of constructing mathematical and computer models of digital twins of a gerotor oil pump. Calculations were carried out for the pump with a modified design.
