Abstract
This paper introduces the concept of a Digital Twin (DT) for the purpose of replicating the engine performance and operation of large 2-stroke engines in the maritime industry. Particularly interesting is the fact that the low engine speeds prevailing for this engine type (60-120 rpm) enable the deployment of physical 1D-CFD models at a high modelling fidelity (detailed air path, predictive combustion, etc.). Therefore, an approach for the development of a real-time and transient capable DT model is presented. General feasibility of the approach and real-time capability have been verified (offline). Furthermore, an outlook is given on the application potential of the DT in terms of the engine’s design process, the engine operation as well as the virtual simulation and testing possibilities.
