Two-dimensional flow vector measurement based on all-fiber laser feedback frequency-shifted multiplexing technology

JIE li KEYAN liU QI YU HONGTAO li BENli YU liANG LU Information Materials and Intelligent Sensing Laboratory of Anhui Province Anhui UniversityHefei 230601China Key Laboratory of Opto-Electronic Information Acquisition and Manipulation of Ministry of Education Anhui UniversityHefei 230601China School of Physics and Optoelectronic Engineering Anhui UniversityHefei 230601China School of Optics and Photonics Beijing Institute of TechnologyBeijing 100081China

The decomposition and identification of signals are crucial for flow vector acquisition in a multi-dimensional measurement. Here, we proposed a two-dimensional(2.) flow vector measurement system based on all-fiber laser feedback frequency-shifted multiplexing technology. The reliable performance of the system is characterized by experimental verification and numerical simulation. An orthogonal dual-beam structure is employed to eliminate the impact of an unknown incident angle in the practical application. Meanwhile, the vector velocity signals in 2. can be decomposed into one-dimensional(1.) scalar signals by adopting the frequency-shifted multiplexing,which makes it easy to obtain the vector information and velocity distribution of fluid motion through the self-mixing interference frequency spectrum.

RDF流化床燃烧过程NO_x生成比较研究

引用

燃料化学学报 2005年第5期33卷 633-636页

作者：赵松李海滨阎常峰赵增立陈勇中国科学院广州能源研究所

NO_x formation behaviors of two kinds of RDF (Refuse Derived Fuel) samples with different N content were studied using a fluidized bed combustor. The results show that RDF samples are easily to be combusted in the fluidized bed reactor and the combustion process is stable without external energy. The distribution of NO_x contents depends on the temperature distribution along the height of the fluidized bed. Under the same operation conditions, the higher nitrogen content in the RDF sample leads to higher NO_x concentration in the flue gas. Both the extra air ratio and the injection of secondary air can affect the NO_x formation characteristics, especially for the RDF with high nitrogen content.
