通过解析和数值模拟表明，轴对称圆柱和球形多孔介质燃烧器（以下简称PMB）内火焰前缘的定位不仅取决于燃料流量和系统参数，还取决于燃烧点燃坐标。在一定参数范围内，燃烧锋面从其初始点火位置移动不明显。结果表明，以燃料流量、混合气热含量和PMB外半径为控制参数，PMB外边界的热损失决定了其特定的特性。
It is shown analytically and by means of numerical simulation that flame front localization inside axis-symmetric cylindrical and spherical porous media burners (hereinafter PMB) is not defined only by fuel flow rate and system parameters, but also depends on combustion ignition coordinate. In a certain parameter range, combustion front does not move significantly from the place of its initial ignition. It is shown that heat losses at the outer boundary of PMB determine the specified peculiarities, with fuel flow rate, heat content of the mixture and the PMB external radius being the governing parameters.
