分别在长９ｍ、内径０．１４ｍ与长１２ｍ、内径０．１４ｍ配有特殊喷雾和喷粉系统的大型水平燃烧管中，对戊烷气云与铝粉粉尘的燃烧加速诱导激波现象进行了实验研究，其结果反映了气云与粉尘悬浮流火焰在管内的传播规律。基于双流体模型，利用分裂格式、ＭａｃＣｏｒｍａｃｋ格式及ＴＶＤ格式对两相反应流的基本方程进行了数值求解，计算结果与实验结果较为吻合。
In the large-scale horizontal combustion tube of 9m in length, 0.14m in length and 12m in length, 0.14m in inner diameter and equipped with a special spray and dusting system respectively, the phenomena of accelerating shock induced combustion of pentane gas cloud and aluminum dust were carried out Experimental results show that the flame of gas cloud and dust suspension flow in the pipe. Based on the dual fluid model, the basic equations of the two-phase reaction flow are numerically solved by using the splitting scheme, the MacCormack scheme and the TVD scheme. The calculated results agree well with the experimental results.
