【摘要】 通过对新型主燃烧器的冷态试验,得到了其冷态流场的分布状况。采用五孔探针对这种新型主燃烧器出口流场进行了测量。本文介绍了五孔探针的标定,研究了不同旋流叶片角度对燃烧器出口速度场的影响。分析了各个工况的轴向,切向,径向速度的变化状况及其扩展角。通过分析得到,这种燃烧器比传统燃烧器更具优越性。这次冷态试验研究,为进一步研究奠定了一定的理论基础。更多还原

【Abstract】 Through the cold-state test of this novel combustor, the cold aerodynamical field of it can be obtained . In here Five-Hole probe was used to measure the exit flow field of it .First the standardization of the Five-Hole probe was introduced ,then the variation of the exit velocity was studied when changing the angle of the swirling blades. At last,the variation of axial,tangential,radial velocity and jet expansion angles were analyzed.The cold-state test research can be the fundation of future study about it.更多还原
