RÉSUMÉ

Three-dimensional Direct Numerical Simulation (DNS) is used to study reaction in a non-premixed turbulent plane wall-jet. The flow is compressible and involves a reaction between an oxidizer and a fuel species The main objective of this study is to use DNS for validation and evaluation of different non-premixed combustion modeling tools. As the first step of this assessment, we have focused on RANS modeling aspects, distinguishing both the heat-release effects and the influences due to the presence of solid-walls. The present study adds to our previous knowledge on the behavior of models in different flow geometries.
