A new coupling method for simulating combustion processes

18.03.2008
The FOCUS project was carried out between 2005 and 2007 by Olivier Gicquel, his research team at the EM2C laboratory of the Ecole Centrale of Paris, and the IDRIS team at CNRS in France.

Using DEISA research infrastructure the researchers have developed a new method for simulating combustion processes that will have a real and practical impact on a number of industrial applications.

Combustion is involved in more than 80% of primary energy conversion processes worldwide. It is used, for example, in aeronautical and ground transportation, waste incineration and in various other industries in which burners and engines are required.

Optimization of burners has led to increased levels of complexity and design innovation. This very complexity increases the likelihood that the burners will malfunction, for example through combustion instabilities. Because the developments of industrial burner prototypes can be very expensive, numerical simulation of combustion processes has become compulsory.

Various different methods exist for performing these simulations. The most recent is called Large Eddy Simulation (LES), and can be viewed as an intermediate technique between direct numerical simulation and classical modelization. Under this approach, larger turbulent motions of the flow field are explicitly computed and resolved, whereas the effects of the smaller ones are only modelled.

To gain a better insight into the full process, the researchers of the FOCUS group have developed an original approach. This proposed approach takes advantage of an efficient coupling between an LES solver and codes devoted to radiative heat transfers, where data exchanges occur at time intervals controlled by the physical times of each phenomenon.

“This project is innovative both from a theoretical point of view and in terms of the numerical aspects, with the development of new models in state-of-the-art simulations”, says Olivier Gicquel, a researcher at the EM2C laboratory and one of the leaders of the FOCUS project.

Numerical simulations of turbulent reacting flows including pollutant formation and radiative heat transfers require not only well-adapted models, but also large computational resources. Research infrastructures like DEISA are therefore very much needed in this area.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
