Abstract

Based on the stationary one-dimensional model, the combustion process for a methane–air mixture in a slot matrix is simulated from the metal plates. The region of stable combustion is found and the possibility of such combustion in a wide range of the change in the flow rate of the gas mixture is explained. It is found that an increased length of the plates leads to an expansion of the stable combustion limits, both in power density and in the stoichiometric coefficient. The possibility of reaching a high burning power density of about 300 W/cm2 in the matrix from plane-parallel plates is shown. The fraction of power carried away by the radiational flux can reach 0.45 at the lower combustion limit.

插槽矩阵中混合混合物的燃烧

摘要

基于固定的一维模型,从金属板上模拟了缝隙矩阵中甲烷-空气混合物的燃烧过程。找到了稳定燃烧的区域,并说明了在气体混合物流量变化很大的范围内进行这种燃烧的可能性。已经发现,增加板的长度导致在功率密度和化学计量系数方面的稳定燃烧极限的扩大。示出了从平面平行的板在基质中达到约300W / cm 2的高燃烧功率密度的可能性。在较低的燃烧极限下,辐射通量带走的功率比例可以达到0.45。
