Numerical simulation of reactive flows: Internal combustion engines
The development efficient and clean internal combustion engines requires a detailed description and a deep understanding of the flow and the chemical processes. Finite volume methods based on open-source programs are used to simulate these processes. Extensive experimental capabilities provide the basis for the validation of existing and the development of new models and numerical methods.

Numerical simulation of reactive flows: Nanoparticle synthesis
Nanoparticles form the basis of many novel materials. A core competence at the UDE is the synthesis of such particles in gas-phase flow reactors. The modeling and simulation of particle-laden, chemically reacting flows is essential to improve the understanding of the processes, to design of reactors and to scale-up laboratory experiments to production facilities.

Complex and multiphase flows: Flow simulation in the nasal cavity
Modern imaging diagnostics techniques such as computer tomography (CT) and magnetic resonance imaging (MRI) provide only a static picture of the main nasal cavity. The simulation of the unsteady flow inside the nose extends this diagnostics technique for the insight into the interaction between the inhaled air and the mucous membrane. Besides the calculation of the flow field and the resulting forces one can investigate the air-conditioning and filtering function of the nose. Thus, the numerical simulation contributes to a better understanding of mass and heat transport in the human nasal cavity.
