Uittreksel

The purpose of the project regards the study of turbulent combustion with hydrogen as the main fuel. RANS and LES models based on the reduction technique Flamelet Generated Manifolds, FGM, will be developed. A particular focus on preferential diffusion effects will be taken into account. This phenomenon is associated with the fact that in the reaction the major species involved have different diffusion velocity. Preferential diffusion governs thermo-diffusivity instabilities. Additionally we study phenomena such as partial unpremixedness, local extinction, wrinkling of flames, which interact with turbulence in a complicated way. The instability problems are also related with changes in enthalpy and element mass fraction and depend on local flame stretch.
