Numerical simulations of the interaction of an H2-02 flame and a wall are performed. Two situtations are considered: a premixed flame propagating towards the wall and a diffusion flame staying at a distance from the wall. In both cases the thermal fluxes to the wall are evaluated during the simulation and the maximal value, as well as the interaction duration, are compared. Results show that the premixed flame leads to high fluxes to the wall, during a short time before quenching. The diffusion flame gives lower values for the maximum flux, but for a longer time. Finally the total energy transferred to the wall is comparable for both flames.
