Development of simulation software for novel combustion technologies

New combustion technologies are more than ever on the agenda, especially in the current complex energy scenario. However, the physical and chemical effects present in these new combustion modes are not yet fully understood.

Combustion technology provides more than 70% of the energy support in Norway and more than 90% of our worldwide energy support. Besides Power Energy, combustion technologieas are used in Aerospace, Aviation, Automotive, Oil&Gas, Firing, Chemical industries, etc. Severe environmental requirements and international agreements on reduction of climate gases (CO2) and pollutant emissions (CO, NOx, soot, particles, etc.) raise a continuous demand for improved combustion technology. Moreover, improved efficiency of biomass energy conversion can be achieved by gasification of biomass and subsequent combustion in gas turbines. This has similarities with, but also distinctions from, coal-and natural-gas utilization. Efficient and clean utilization of biomass depends (among other) on combustion technology designed for this purpose. Both with regards to these technologies and in general, abatement of pollutants such as NOx (mainly from fuel nitrogen) is important.

edcPisoFoam – innovative solver for complex multi-physical problems including heat transfer and combustion. The latest release includes:
- The core LES/DNS solver for compressible flows and Eddy Dissipation Concept, adapted for other turbulence-chemistry interaction models and the conventional RANS/URANS as well as hybrid SAS/DES approaches;
- Chemical kinetics of any complexity (two, state-of-the-art Stiff ODEs integrators RADAU5 and LSODA);
- Solver covers premixed, non-premixed and partial-premixed combustion regimes and precise in simulation of unsteady combustion physics (lean-blow out, combustion dynamics, flashback);
- Detailed verification and validation based on well-known combustion benchmarks (flames from Sandia National Lab, Volvo test rig, PPJB, etc.), as well as side-to-side comparison with Ansys Fluent. Main results have been published in three PhD thesis and several (9+) publications;
- Solver’s performance and scalability is compatible with other commercial codes (Ansys Fluent, Star-CCM+);
