N2 - Experimental data on the diffusion combustion of a round hydrogen microjet in a concurrent coaxial flow are presented. The effects on the combustion of a concurrent air flow and an air flow premixed with nanopowder of TiO2 are of interest.

Combustion events found in these conditions are similar to those observed in the previous studies on the diffusion combustion of hydrogen microjets at subsonic and supersonic velocities. In a subsonic range, the so-called “bottleneck-flame region” is generated close to the nozzle exit, while in high-speed conditions, the flame separates from the nozzle.
