| 摘 要： | 通过二维数值模型研究了多孔介质燃烧-换热器。在宽广的工况范围内,研究多孔介质燃烧-换热器内的温度、速度分布和压力损失,研究主要工作参数过量空气系数和功率对换热管总的热效率的影响。结果表明,过量空气系数和功率对总的热效率有显著的影响,随二者的增大,总的热效率降低。实验验证了数值计算结果的有效性。

| Abstract: | 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... |
