Abstract

Results of studying interaction of two colliding axisymmetric laminar microjets of hydrogen in the course of their diffusion combustion are reported. Gas exhaustion occurs with identical velocities through pairs of micronozzles, which are thin-walled cylindrical tubes with an inner diameter of 200 \(\mu\)m. The transverse positions of the tubes with respect to each other are changed during the experiment. Specific features of flame formation from two interacting microjets are found for different transverse positions of the tubes, and the results are compared with flames of single microjets with the same exhaustion velocity.

两个氢射流碰撞时火焰形成的具体特征

报道了两种轴对称层流微射流在扩散燃烧过程中相互作用的研究结果。气体通过一对微喷嘴以相同的速度排出，微喷嘴是内径为200 \(\mu\) m的薄壁圆柱形管。在实验过程中，这些管相对于彼此的横向位置发生变化。发现了两束微射流相互作用时在不同管道横向位置下火焰形成的特定特征，并与相同耗尽速度下单束微射流的火焰形成结果进行了比较。
