| Abstract: | The double over critical nozzles device can mix two kinds of gases quickly and uniformly.Good capability and simple configuration,the pressure range which can be applied in filling the mixture was upgraded 40% higher than that of the critical nozzles.With boundary layer modification,virtual calibration,color spectrum measurement,the mixed result was proved to be fairly good.This device can be used to fill mixture gases in some combustion and detonation experiments. |
