Flame Quenching at Cold Walls


Basics

A laminar premixed flame that propagates in the vicinity of a cold wall may be quenched due to the high heat losses to the wall. This usually leads to large amounts of unburned hydrocarbons close to the wall. The rate of oxidation of these unburned hydrocarbons is controlled by the diffusive transport towards the hot gases. Several aspects such influence of wall temperature, pressure, choice of fuel and modelling of diffusive fluxes are investigated.
