激光多普勒测速技术应用于浓缩燃烧器湍流流场的测量
Measurements of the Turbulence Field of the Pulverized Coal Bias Bruner with Laser Doppler Velocimetry
摘要
在煤粉浓缩燃烧器中加入示踪颗粒，利用激光多普勒测速技术对湍流流场的速度场及湍流参数进行测量研究，通过自动数据采集及处理分析系统，获得不同钝体结构的煤粉浓缩燃烧器的速度及湍流强度分布，为钝体的选型和燃烧器的设计、着火燃烧机理的分析提供了理论依据。
Abstract
By using Laser Doppler Velocimetry(LDV) and adding a tracing particle into the PC burner, the turbulence parameters and the velocity field of the burner outlet are measured and analysed.The turbulence and the velocity distribution of the pulverized coal bias burner with different bluffbody have been achieved by the automatic data processing systems. The theoretical foundation for the selection of bluffbody, design and ignition mechanism of the burner are given.
