Hydrodynamic and Thermal Processes in the Oil Cooler of the Lubrication System of Diesel Engines: Numerical Simulation

This article presents the results that serve as a methodological basis for creating a digital twin of an oil cooler in a diesel engine lubrication system. At the first stage, the oil cooler was decomposed into individual components, and mathematical and computer models of the oil cooler components in the engine lubrication system were developed. At the second stage, numerical modeling of hydrodynamic and thermal processes during the operation of the oil cooler components was conducted to verify and validate the models based on experimental data. Based on the calculations, recommendations were developed to improve the accuracy of constructing mathematical and computer models of the oil cooler’s digital twins, as well as approaches to enhance the design.
