Résumé
A study of multicomponent reacting channel flows with significant heat transfer and low Mach number has been performed using a set of direct and large eddy simulations. The use of LES computations was needed to analyze accurate and relevant data of such flows at a sufficient Reynolds number and reasonable computational cost. The analysis of these data will be detailed leading to the development of an analytical wall model for predicting the total shear stress and heat flux at the wall.
