摘要
本文描述了激波卷扬可燃粉尘床形成燃烧反应边界层的理论模型,由此揭示出该反应边界层的基本结构由诱导区、反应区、扩散区构成.另外,燃烧粉尘云轮廓及颗粒点火时间的理论值与实验结果较一致,说明此模型能很好地描述上述流动特征.
In this paper, a comprehensive model of combusting dusty boundary layer induced by a shock sweeping over a combust dust layer is presented. According to the model, the reactive boundary layer consists of an induction zone, a reaction zone and a diffusion zone. The theoretical results of dust cloud height and particle ignition time are in good agreement with those of experiments.
