摘　　要：利用FLUENT软件对所设计的多射流切圆预混多孔介质燃烧器进行流场模拟,主要研究流道结构、预混室的几何结构、空气和燃气速度及压力等因素对空气系数的影响,并重点分析速度、压力流场与湍流动能及湍流动能耗散率的变化分布,确定合理的预混室参数。Using Fluent software, the flow field of the premixed flow porous media burner was simulated. The influences of the flow channel structure, geometry structure of the pre-mix chamber, air and gas velocity on air coefficient were mainly discussed. The velocitie, pressure, turbulence kinetic energy and turbulence kinetic energy dissipation rate were analyzed in detail. Methane and air combustion process was determined reasonably.
