Research carried out at the Aerothermochemistry and Combustion Systems Laboratory is guided by the vision of “Near-Zero-Combustion Systems” for freight and personnel transportation as well as decentralized (co-/tri-)generation of power, heat (and cooling).
Accomplishment of this ambitious, long-term oriented strategic goal requires deep insight into the fundamentals of turbulence-thermochemistry interactions in unsteady combustion in IC engines.
For this purpose we develop and apply synergetically non-intrusive (laser-based) diagnostics in optically accessible test-rigs and advanced modelling/simulation methods in the area of Computational/Reactive Fluiddynamics (CRFD). The latter span the entire range of DNS through LES to RANS methods as well the Entropic Lattice Boltzmann approach (group headed by Prof. I. Karlin). Knowledge transfer to industry and support for the development of new products is a challenging but highly rewarding goal. On the experimental side we provide input to our industrial partners in regard to optimization of innovative multi-mode, multi-fuel combustion processes and on the simulation side we develop and validate physics-based phenomenological combustion and pollutant emissions methods for “off-line” design of combustion systems on one hand as well as mean-value-models serving as virtual sensors for monitoring and controls application in IC Engines and Powertrains.
Finally, as several emerging technologies appear to challenge the dominance of combustion processes in transportation, it is of vital importance to be able to understand and assess the comparative performance of all competing technologies for the specific purpose including the non-propulsive energy demand of private and commercial vehicles. Therefore an Energy Systems Modeling Group has been established several years ago at LAV that serves as strategy development tool while providing simultaneously an important interface to the “Strategic Guidance Project” of the SCCER “Efficient Mobility”. In addition this group provides advice to mobility and energy service providers with regard to the optimization of their product portfolio.
