摘要: 微燃烧器与阻火器淬火单元均为可燃气体燃烧的微通道,目前对微燃烧器的研究较充分,而对阻火器淬火单元的研究较少. 本工作概述了影响火焰在微通道内传播的因素,指出对各因素的研究还需深入,有利于澄清争议;简述了火焰在微通道内传播的数学模型的研究进展,提出微通道内流体流动流型的判定亟需完善;确定在高速爆轰条件下,阻火器内的流动为湍流;推荐将雷诺应力湍流模型与层流有限速率模型结合进行阻火器内高速爆轰火焰传播的数值模拟,推荐采用以密度为基础的算法进行求解;指出了微通道内火焰传播研究的成果与不足,展望了其发展方向.

Abstract: Both the microcombustor and the quenching units of the flame arrestors are microchannels containing combustible gas burning. Although the researches on the microcombustor are abundant, the study of the quenching units in the flame arrestors is relatively scarce. In this work the principal factors affecting the flame propagation in the microchannels are summarized. It is shown that a more systematic study is desired to settle the disputes. The advance of the mathematical model for the flame propagation in the microchannels is reviewed. It is proposed that the fluid flow pattern in the microchannel is worth discussing. It is determined that the flow in the flame arrestor is turbulent under high-speed detonation conditions. The combination of the Reynolds stress model with the laminar finite rate model is recommended here to be employed for the numerical simulation of detonation flame propagation in the flame arrestors. A density-based algorithm is recommended. In the concluding remark, research achievements and shortcomings in the investigation of flame propagation in the microchannels are pointed out, and the outlook is also addressed.
