大型水平管道中环氧丙烷-铝粉-空气混和物爆燃转爆轰的实验研究
Experimental Research of Deflagration to Detonation Transition of Epoxypropane-Aluminum-Air Mixtures in Large-Scale Tube
摘要
Abstract
Motivated by the current interest in the mechanism of the deflagration to detonation transition （DDT）,the DDT experiments of epoxypropane-air mixture and epoxypropane-aluminum-air mixture are carried out by a large-scale tube （32.4 m long and 0. 199 inner diameter）. The processes of DDT in multi-phase clouds are analyzed,and the mixtures with different concentrations are compared. The self-sustained detonation waves are formed in the epoxypropane-air mixture with epoxypropane concentration of 513 g/m3 and epoxypropane-aluminum-air mixture with epoxypropane and aluminum concentrations of 237 and 643 g/m3 ,and moreover the cell size of the detonation are 0.28 and 0.5 m, respectively.关键词
