The objective of the present work is experimental investigation of the diffusion combustion of hydrogen microjets emanating from various micronozzles including a Laval supersonic quasi-micronozzles of different configuration and size. In what follows we focus on the characteristics of the «bottleneck flame region» depending on the microjet efflux velocity, the influence of this particular flow area upon heating of a thick-walled nozzle, and the effect of heating on the origination of the «bottleneck flame region» at variation of jet velocity up to the transonic range. Also we are interested in indications which could be helpful in experimental work to distinguish between subsonic and supersonic regimes of hydrogen jets and their combustion.[
