摘要
本文描述了一种利用多通道高温计测量汽油云雾爆轰瞬态温度的方法,这种方法既适合云雾爆轰辐射充满光纤接收角,又适用辐射部分进入光纤接收角,我们在激波管内,以光纤传输光能,用多通道高温计测量了汽油云雾中氧气、氮气对爆轰温度的影响。研究表明:对于富含汽油的混合物,增加氧含量可使爆轰温度增加;增加氮含量可导致爆轰温度下降,它和利用传感器测量结果吻合。
A multi-wavelength pyrometer technique that can be used to measure instantaneous detonation temperature for gasoline spray is described in this paper with the entire field of view of the receiving fibres either filled by gas or not. The influence of oxygen (or nitrogen) in gasoline spray on the detonation temperature is measured usinge a multi-wavelength pyrometer with quartz fibres. The results show that the detonation temperature for gasoline spray increases with the increase of oxygen and decreases with the increase of nitrogen. It coincides with the results of measurement using quartz gauges.
