摘要: Abstract Based on RQL (rich-burn/quick-quench/lean-burn) low emission combustion technology, a RP-3 fuelled high temperature rise combustor was proposed. The flow and radicals (OH∗, CH∗, NO∗) distribution of were investigated by Particle Image Velocimetry (PIV) chemiluminescence imaging. Although the change primary holes structure has great influence characteristics reaction zone, airflow same effect zone. High-brightness values CH∗ mainly occurred in shear layer under parallel airflow, zone exhibited smooth boundary. When swirling vertical airflows acted boundary luminance reduced became wrinkled. starting boundaries NO∗ OH∗ basically coincident, although end lagged. axial position located at H/2, compared with symmetric structure, mean residence time area NO-producing region quenching staggered could be about 20% 47%, respectively.
