Abstract

The non-premixed flamelet model of Peters [1] (model1), which does not include preferential diffusion effects is investigated. Two similar models are presented, but without the assumption of unity Lewis numbers. One of these models was derived by Peters & Pitsch [2] (model2), while the other one was derived by Delhaye [3] (model3). A numerical analysis shows that preferential diffusion effects can not be neglected a-priori when more realistic Lewisnumbers are considered. Furthermore, two models for the scalar dissipation rate are investigated, and it is shown that density variations are important.
