The experimental research of the relationship between flame and explosion wave in gas explosion

摘要

This paper studies the relationship between flame and explosion wave in gas explosion on the basis of experiment. The result of study indicates that the transmission speed of explosion wave exceeds that of flame when gas explosion happens. Time difference between flame and explosion wave depends not only on the position, but also on the number of barriers. With the increase of barriers, speedup action of flame exceeds that fo explosion wave. The transmission law of flame and explosion wave can be described as: T=mX(L/D)+b; With the increase of barriers, linear degree of the transmission decreases and non-linear degree increases accordingly.
