摘要

摘要这项工作利用光学诊断方法研究了从动力燃烧到扩散燃烧的过渡。实验获得了从 2×20 毫米狭缝流向空气的氢火焰前缘附近气体的温度场、成分和速度数据。利用能量、动量和质量传递方程的平衡方法，获得了燃烧产物形成率、放热强度和压力的分布情况。结果表明，在向扩散燃烧过渡的过程中，沿火焰长度方向的放热量下降速度比水形成的速度慢。

Studying the development and interrelation of transfer processes during the combustion of a hydrogen jet flowing from a slit into the air

This work examines the transition from kinetic to diffusion combustion using optical diagnostic methods. Experimental data were obtained on the temperature fields, composition and velocity of gas near the leading edge of a hydrogen flame flowing from a 2×20 mm slit into the air. The distribution of the rate of combustion product formation, the intensity of heat release and pressure was obtained using the method of balances in equations of energy, momentum, and mass transfer. It is shown that during the transition to diffusion combustion, heat release along the flame length decreases more slowly than the rate of water formation.

期刊介绍： The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
