| 摘 要： | 对带有N2稀释的中热值合成气旋流燃烧火焰的热态流场进行了PIV(粒子图像速度仪)测量,分析了不同稀释量对燃烧流场的影响规律.实验结果表明,N2的存在主要改变了射流区的尺寸,火焰的宽度基本不受影响,最高回流速度随稀释量的增加而增大,回流区内的脉动则随之减小,同时稀释量的增加会降低回流区内的湍动能,从而引起火焰温度的降低.

| Abstract: | A PIV(Particle Image Velocimetry) measurement was performed of a combustion flame hot state cyclone flow field of a medium heating value synthetic gas diluted with nitrogen.Moreover,the law governing the influence of different nitrogen dilution amounts on the combustion flow field was analyzed.The test results show that the presence of nitrogen can mainly change the size of the jet flow zone and the width of the flame is basically not affected.The maximum return flow speed will increase with an increase of ... |
