Abstract
Chemically reacting flows develop specific features at small scales as observed from Direct Numerical Simulations of three dimensional shear flows. Reaction develops along eddy structures with intermittency in space depending on chemical characteristics. Flowchemistry interactions can be interpreted in terms of typical time and length scales. Real flows have often to be approached with Large Eddy Simulations. The examples which are given here are associated with supersonic combustion projects. Hydrogen-oxygen reaction is considered and the subgrid model is efficiently provided by the numerical scheme for both velocity and concentration fields.
