Abstract
The development and structure of the mixing and combustion process of sub- and supersonic hydrogen/air flames was investigated by means of o ptical measurement techniques. The experiments showed that the develop ment of the mixing jet can be predicted with a new, given formula. The use of a rearward facing step enabled the stabilization of the flame under all operation conditions of the combustion chamber up to superso nic speed. A given model for the stabilization of high-speed hydrogen/ air flames explains the influence of turbulent flow structures on the combustion process.
