| Abstract | In micro and mesoscale combustion, there exists strong flame-wall interaction and flame can be quenched by thermal and kinetic mechanisms. In the present study, the thermal and kinetic quenching mechanisms are studied. We provide a general theoretical description of flame propagation in a tube with heat loss and radical quenching on the wall. The thermally sensitive intermediate kinetics and surface radical quenching reaction are considered and a correlation, which describes the change of the flame propagation speed with heat loss and radical quenching coefficients, is derived. Based on this correlation, the effects of wall temperature and cross-over temperature on flame speed and quenching limit are examined. It is found that the radical quenching effect becomes stronger at higher wall temperature and lower cross-over temperature. |
