摘要

为了测量爆震管中从爆燃到爆震转捩距离

研制了一套基于对比电路的离子探针系统。通过该系统测量爆震管中火焰传播速度的轴向分布

确定了爆燃到爆震的转捩距离。系统结构简单

造价低廉

可用于高温环境下测量。运用该系统测量的乙炔与氧气混合气从爆燃到爆震转捩的距离

其结果与采用高频响的压力传感器系统的测量结果一致。

Abstract

In order to obtain the Deflagration to Detonation Transition (DDT) distance in the detonative tube

an ion probe system based on comparative electric circuit was made.This system was used to measure the flame propagation velocities along the tube

and furthermore to determine the DDT distance.As compared with high frequency pressure transducers

this system was simpler and cheaper

especially it could be used in the high temperature condition for a longer time.In this paper

the DDT distances of acetylene and oxygen mixture were measured with this system

and the results were consistent with that of high frequency pressure transducers.
