Abstract

The results of experimental investigations of the features of diffusion combustion during the interaction of a round supersonic microjet of air in the center and a coaxial (coflowing ring) jet of hydrogen. Such combustion is accompanied by a number of new phenomena: the formation of a cone-shaped flame near the nozzle сutoff, the locking of the combustion region in this cone, the presence of small-scale supersonic cells in the resulting flow, and the formation of laminar sections and their turbulization.

超声超音速圆形微射流与氢气的同轴（同流环）射流相互作用时的扩散燃烧

摘要

在中心的圆形超音速微型喷气与氢气的同轴（同流环）喷气相互作用过程中扩散燃烧特征的实验研究结果。这种燃烧伴随着许多新现象：在喷嘴utut附近形成锥形火焰，将燃烧区域锁定在该锥形中，在生成的流中存在小规模超音速单元以及形成层截面及其湍流。
