Abstract

基于羟基标记示踪速度测量技术，研究了基于该技术中激光光解水产生的OH-进行温度测量的双色平面激光诱导荧光（PLIF）方法和荧光强度测温方法，进而开发了一种新的速度、温度同时测量技术，并在电加热流场及超燃冲压发动机流场进行了测量验证。在室温至900 K的温度范围内，与热电偶温度测量结果比，基于光解OH-的双色PLIF温度测量的平均标准偏差为12.1 K，基于光解OH-荧光强度的温度测量最大偏差为16.8 K，速度测量不确定度在1%以内。在超燃冲压发动机流场中，利用CARS温度测量数据作为温度测量标定点，获得了标记线上温度、速度的同时测量结果，其中所得温度与CARS温度测量结果的最大偏差为44 K。

期刊介绍： Researching is owned by Chinese Laser Press (CLP), which is established by Shanghai Institute of Optics and Fine Mechanics and Chinese Optical Society in 2009. Nowadays, CLP publishes 11 journals and manages three online platforms. Journal publishing activities include both traditional and digital models, and the first journal can be traced back to 1964. The CLP Online Library includes the CLP journals and partnered ones in China, and provides literature and intelligence services for users. The product platform, named as OEShow, connects sellers and buyers of optoelectronics products. Researching (formerly known as The CLP Publishing) is featured with stable operation and leading technology, collects CLP journals and partnered optics and photonics journals, and provides readers an optical publishing platform with global influence. CLP is on the way of building a modern publishing group combining traditional business and digital publishing.
