摘要
运用CCD摄像机对一种全新的同轴旋转分层流低NOx燃烧器出口空气动力特性进行了可视化研究 ,并对采集的图像进行了一系列处理。定义了一次风扩展角和一次风转捩长度 ,并对其变化规律进行了研究 ,为同轴旋转分层流燃烧器分层机理的研究打下了基础 。
Ari dynamic field in the original co axial swirl stratified flow low NOx burner exit has been studied by virtual experiment with CCD video.The obtained images are processed systematically .The spread angle and turn point length have been defined and their change law has been researched, which is the spade work to study stratification mechanism of co axial swirl stratified flow burner and provides reference on adjusting burner running.
