摘要這篇文章描述擴散火焰之光學Rayleigh 散射溫度測量法。首先對此光學溫度量測之原理 ,設備以及測量步驟加以說明。根據原理,有效 應用此測量法之最簡單方法是使用特殊的燃料 及助燃劑。實驗結果證明,以此方法所得到之 火焰溫度及分布是非常合理的。
This paper describes an optical Rayleigh scattering temperature measurement in diffusion flames. The principle setup and procedure of this technique were described. According to the principle of this technique, a constant Rayleigh cross section throughout the measurement domain is the simplest way to achieve this measurement. This can be done by using special fuel and oxidizer mixtures. It was shown in this study that the fuel mixture contained methane and light molecules, such as helium, did not exhibit constant Rayleigh cross section, which could result in incorrect temperature information. After careful selection of the fuel and oxidizer mixtures, the obtained data showed that the highest temperature of the flame is around 1950K, and the maximum temperature occurs at the flame sheet location and decreases toward both fuel and oxidizer sides of the flame, as expected.;This paper describes an optical Rayleigh scattering temperature measurement in diffusion flames.
