摘要
本文研究了固体燃料在不同的环境辐射条件下燃烧过程的火焰传播速度.首先,建立了考虑周围环境辐射的固体燃料燃烧的一维模型,并推导了其无量纲方程,针对内部带有不反应导热体的固体燃料棒中的求解结果表明,环境辐射温度和固体燃料的火焰传播速度存在着线性关系;进而,通过初步的实验测量结果验证了该线性关系.
In this paper, the effects of ambient are theoretically and experimentally investigated. radiation on the flame propagation of solid fuels First, a one-dimensional combustion model that accounts for the heat radiation around solid fuels is established, and the dimensionless equation is derived. As for a case of a solid fuel stick with a heat conductor inside, the related numerical results indicate that there exists a linear relationship between the flame speed and the ambience temperature. Finally, the linear relationship is verified by the experiment of solid fuel combustion.
