Investigation of the 3-D Hydrogen Flame Structure in a Supersonic High- Temperature Air Flow by Optical Methods

摘要

In this work the experimental results of research of a plume structure at axial hydrogen injection in a supersonic high-temperature air jet are presented. Two levels of temperatures are compared. One of them (1500-2000 K) is usually achieved in the ground experimental facility with a long period of action. The other level of temperature (2500-2700 K) is characteristic for installations with a short period of action.
