The two-dimensional numerical investigations on the porous media combustion-heater were presented.Temperature distribution,velocity profiles,and pressure loss were investigated in a wide range of operation parameters.Attention was focused on the influence of the dominating parameters,i. e.,the excess air ratio and firing rate,on the thermal efficiency.The results showed that the excess air ratio and firing rate had significant influence on thermal efficiency,and the overall thermal efficiency decreased with increasing excess air ratio or firing rate.Numerical results were validated against experiment data.
