A CFD study on fundamental flame characteristics of premixed hydrogen-air combustion in a planar porous micro-combustor is carried out by using one-temperature model and two-temperature model. The differences of the results of two calculation models and the suitable conditions of one-temperature model are discussed. The numerical results indicate that the one-temperature model gives a lower flame temperature and a closer flame position to the upstream than the two-temperature counterpart. The differences of flame temperature and position between two models reduce with the decrease of ks and the increase of ?.
