The applications of catalytic combustion technology cover a number of future strategic industries and therefore are of interests to both fundamental and applied combustion research.In many catalytic combustion processes,gas phase flames are ignited and intricately coupled with the catalytic reaction pathway.This article briefly reviews the latest research progress on premixed laminar combustion in catalytic channels coated with commonly used noble metals,including the controlling equations,numerical models,and conditions of flame ignition and propagation during coupled catalytic-gaseous combustion in microchannels.Several key fuels were reviewed,including hydrogen,syngas,methane,propane,n-decane,etc.Moreover,their distinct flame shapes,propen-sities of both fuel-lean and fuel-rich flames,and especially the determining factors of chemistry,flow and heat and mass transfer were discussed.
