Abstract

A series of experiments are conducted with the use of a shock tube at the Institute of Mechanics, Moscow State University to determine radiation absorption spectra in shock-heated oxygen in the wavelength range of 213–260 nm at a gas pressure of 1 Torr and shock wave velocities ranging from 3.4 to 4.5 km/s. Based on a comparison of the experimental data with the results of calculations using a spectral-kinetic model, the effect of bound–bound and bound–unbound transitions in the Schumann–Runge system on the absorption properties of oxygen is analyzed.

冲击加热氧气吸收特性的实验与理论研究

利用莫斯科国立大学力学研究所的激波管进行了一系列实验，确定了在气体压力为1托、激波速度为3.4 ~ 4.5 km/s的条件下，激波加热氧气在213 ~ 260 nm波长范围内的辐射吸收光谱。在将实验数据与光谱动力学模型计算结果进行比较的基础上，分析了舒曼-龙格体系中结合-结合和结合-非结合跃迁对氧吸收特性的影响。

期刊介绍： Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
