Model-Based Fuel Design


Prof. Dr. rer. nat. Kai Leonhard

Short name:



This junior professorship focuses on the fuel design problem as the key example of a general product design problem. Research will contribute to expanding model-based product design methods to incorporate more complex property and process models. Property models have to link molecular structure to the functional characteristics of the fuel or of the solvent in addition to thermodynamic quantities. Thereby, parameters describing functional characteristic in the engine combustion have to go far beyond Cetane or Octane numbers used today in order to account for effects on future low temperature combustion systems. Process models have to predict constraints for product design such as energetic efficiency or yield and selectivity. The research objective devises systematic strategies for the use of the advanced models and knowledge developed in the IRF-1, IRF-2 and IRF-3 for the targeted design of fuel mixtures and non-conventional solvents built from newly discovered molecules with optimised properties.

Profile Area ECPE

The provision of sustainable energy and materials is clearly one of the major global challenges which were identified in the future strategy of RWTH Aachen University. The profile area Energy, Chemical & Process Engineering (ECPE) addresses the two most important pathways to achieve this goal: Improvements in energy and material efficiency and the transition to renewable sources.

More information on the profile area's key topics can be found here.

RWTH Aachen Profile Areas

RWTH Aachen University is convinced that in order to solve today's complex and multi-faceted problems, universities have to develop appropriate, integrated approaches. The Profile Areas are designed to address interdisciplinary topics and thus to enhance the University’s capability to engage in significant research activities and take on large-scale projects.
