Abstract

A technique for modeling the radiation of shock-heated oxygen by the direct simulation Monte Carlo (DSM) method is described, taking into account the rates of chemical reactions and excitation of vibrational, rotational, and electronic degrees of freedom of oxygen molecules. The simulation results are compared with the experimental data on the measurement of the radiation of shock-heated oxygen in the shock tube of the Institute of Mechanics of Moscow State University.

冲击波后氧气辐射的直接统计建模
考虑到氧分子的化学反应速率以及振动、旋转和电子自由度的激发,介绍了一种通过直接模拟蒙特卡洛(DSM)方法建立冲击加热氧气辐射模型的技术。模拟结果与莫斯科国立大学力学研究所冲击管中测量冲击加热氧气辐射的实验数据进行了比较。

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.
