中文摘要: |
等离子体电弧温度场和流场的研究对其在工业生产中的应用具有重要的意义。文章分析了等离子弧温度场以
及流场检测和计算的研究现状。在等离子弧温度场的检测中,现今光谱诊断法最为方便,所测得的结果较其他检测方法
而言精确度更高;在等离子弧流场的检测中,运用粒子成像测速技术的方法可以检测得到流场分布。在等离子弧温度场
和流场的计算中,数理解析法计算繁琐,需要大量时间。数值模拟的方法更为经济、有效。 |
英文摘要: |
As the research on the temperature and flow field of plasma arc plays an important role in its industry
application, the research status of detection and calculation of temperature and flow field on plasma arc were analyzed.
In the detection of temperature field, spectrometry is most convenient and the result has higher precision than other
methods. In the detection of flow field. the distribution of flow field can be detected in the use of particle image
velocimetry. In the calculation of temperature and flow field. mathematical analysis is complicated and requires a lot of
time. Numerical simulation is more economical and effective. |
