Combustion and Simulation

The project Combustion and Simulation aims to optimize thermodynamic simulation tools that are used during the regular combustion development of hydrogen engines in the future. Hydrogen has some characteristic properties that have a strong impact to some of these tools. The by far most important property of hydrogen is the strong tendency to combustion anomalies. Any simulation tool, that covers the combustion, is heavily affected by the occurrence of combustion anomalies. This is especially true for the widely used computational fluid dynamics, be it three- or one-dimensional.

It is, therefore, a main focus of Hylley, to advance the widely used CFD simulation for the usage in hydrogen engines. The key research in this project is the development of models for the prediction of combustion anomalies like pre-ignition, knocking and backfiring. These models need to consider the influence of charge composition, ignition, degradation, geometry and oil droplets. From the scientific point of view, this is the most demanding objective of the entire project Hylley.
