Abstract

The results of an investigation of the interaction between two colliding axisymmetric laminar microjets of propane-butane mixture with and without diffusion combustion are presented. The gas mixture components flow out through round tubes at the same velocities. In the course of the experiments the lateral position of the tubes with respect to each other was varied with conservation of the angle between them. The distinctive features of the resulting jet formation are established as functions of the transverse position of the tubes. If the tubes lie in the same plane, then the resulting jet is formed in the plane orthogonal to them. This process can be observable in the case of the interaction between the jets both with and without flame. With increase in the jet outflow velocity a region of local discontinuity of the flame front is found to exist.

两股层流气体射流碰撞羽流形成的显着特征

摘要

提出了有和没有扩散燃烧的丙烷-丁烷混合物的两个碰撞轴对称层流微射流之间相互作用的研究结果。气体混合物组分以相同的速度通过圆管流出。在实验过程中，管子相对于彼此的横向位置随着管子之间的角度的保持而变化。所产生的射流形成的独特特征是作为管的横向位置的函数而确定的。如果管子位于同一平面，则产生的射流形成在与它们正交的平面中。在有火焰和无火焰的射流之间相互作用的情况下可以观察到该过程。随着射流流出速度的增加，发现存在火焰前锋的局部不连续区域。
