“We need accurate combustion models, also in times of climate change”

Research profile

Dirk Roekaerts is a Full Professor in the section Energy Technology and Chair of Combustion of Sprays and Particle clouds Turbulent Flows at Eindhoven University of Technology (TU/e). His research at TU/e aims to develop and validate accurate computational models of combustion processes involving particles and droplets, as for instance observed in spray flames in engines and gas turbines as well as biomass conversion systems. More generally, his research concerns reactive flows with phase change and heat transfer as occurring in many energy applications.

The studied systems show complex nonlinear behaviour as a result of the coupling of turbulence and highly temperature dependent chemical reactions. Methods of handling this combine fluid mechanics, thermodynamics and transport phenomena. The main challenge is to find the optimal combination of low computational cost and model accuracy in a certain context or application. This is also a central theme in MSc courses and graduation projects. Validation of computational results with experimental data always plays an important role.

Academic background

Dirk Roekaerts obtained his PhD in Theoretical Physics from Katholieke Universiteit Leuven in Belgium in 1981. Next, during his civil service, he was responsible for organization of activities on ‘Science, Technology and Society’. As a Postdoc Researcher at the Universities of Essen, Germany, and Leuven, Belgium, he went on to investigate links between nonlinear phenomena, supersymmetry and stochastic processes.  From 1987 to 2005 he was a Research Physicist at the Shell Research and Technology Centre in Amsterdam, investigating complex flows in industrial equipment such as furnaces, gasifiers and chemical reactors. From 1991 until 2005 he was part-time professor at Delft University of Technology leading research projects on turbulent reacting flows. In addition to his work at TU/e, Dirk is also a Full professor at Delft University of Technology.
