摘要

摘要使用动力学和连续方法对从环形喷嘴进入低压腔的超音速气体流进行了数值研究。这种气流应用于使用通过轴向通道的电子束的气体喷射等离子体化学技术。研究采用直接模拟蒙特卡洛法，并使用 ANSYS Fluent 软件求解连续方程。结果表明，即使在电子束通道的低密度区域，所得到的解也能很好地相互吻合。由此得出结论，ANSYS Fluent 软件适用于模拟此类流动。

SUPERSONIC GAS FLOW FROM AN ANNULAR NOZZLE INTO A LOW-PRESSURE CHAMBER WITH AN AXIAL CHANNEL: KINETIC AND CONTINUUM SOLUTIONS

Supersonic gas flow from an annular nozzle into a low-pressure chamber is studied numerically using kinetic and continuum approaches. Such flows find applications in gas-jet plasma-chemical technologies using an electron beam passing through an axial channel. The study is performed by using the direct simulation Monte Carlo method and by solving continuum equations using ANSYS Fluent software. It is shown that the solutions obtained are in good agreement with each other even in low-density regions of the electron beam channel. This leads to the conclusion that ANSYS Fluent software is suitable for simulating flows of this type.
