Abstract

In order to make progress in the numerical investigation of practical turbulent propulsion systems, it is necessary to develop accurate Turbulent Combustion Models (TCM). A lot of work has been devoted to this task, particularly in the case of premixed combustion, but much remains to be done. Non-premixed systems are used in many industrial applications, e.g. in Diesel engines or in domestic burners, and it seems appropriate to study in detail turbulent non-premixed reacting flows. Apart from very complex experimental investigations, the only way to carry out such studies seems to be at present time Direct Numerical Simulation (DNS). Of course, an accurate simulation of reacting flows implies in many cases the use of detailed models for reactive and transport processes. We describe in this paper first results concerning such Direct Numerical Simulations of turbulent non-premixed flames using detailed chemistry.
