摘要

摘要利用热成像技术对单层多孔介质中逆新鲜混合物上游传播的过滤燃烧波的温度特性进行了实验研究。通过设计一个模型多孔燃烧器，可以获得固相温度分布在孔隙尺度上的时间演化数据。研究表明，火焰在宏观尺度上的传播伴随着火焰前沿的局部扭曲，以及若干孔隙尺度上热点和低温区域的出现和移动。确定并描述了过滤燃烧波局部动态行为的最常见模式。

Features of Nonstationary Filtration Combustion Wave Propagation in a Model One-Layer Porous Medium

Abstract

Temperature characteristics of a filtration combustion wave propagating upstream against a fresh mixture in a one-layer porous medium is studied experimentally using thermal imaging. The design of a model porous burner allows one to obtain data on the time evolution of the temperature distribution of the solid phase at the pore scale. It is shown that the macroscale propagation of a flame is accompanied by local distortions of its front and the emergence and movement of hot spots and low-temperature regions at the scale of several pores. The most common pattern of the local dynamic behavior of the filtration combustion wave is identified and described.
