外文摘要：Aimed to optimize the design of micro combustor whose chamber based on porous medium wall surface, combustion and flame stability characteristics on porous wall surface with methane/air flat flame were investigated experimentally in this paper. The experimental results show that stable flat flame can be formed on the porous medium surface within given ranges of fuel equivalence ratio and flow rate. When mixture flow rate increasing, the thickness of flame decreases firstly and then increases, and standoff distance of flames decreases quickly and then is unchanged. At higher mean velocity of mixture, the flame moves closer to the porous plate surface, and the minimum distance needing for keeping stable flames decreases. The heat exchange between the porous plate and the mixture can not only preheat mixture but also cool the porous plate.
