摘要

摘要: 在常温常压下,采用PIV技术测量了旋流器套筒为收口套筒时单头部矩形燃烧室主燃区的流场,获得了主燃区速度场和涡量场的详细信息.试验结果表明收口套筒形成了小尺度回流区大角涡的主燃区流场结构;收口套筒对旋转气流的收缩作用可以很好的改善燃烧室内油气的混合.

Abstract: The primary zone flow field of the swirler's convergent sleeve was measured by PIVtechnology under atmospheric pressure and temperature,providing detailed information on the primary zone flow field and vorticity field.The results show that the primary zone flow field of the convergent sleeve has a structure of small recirculation and big corner swirls,and the constriction of convergent sleeve on circumgyrated air could improve the mixing of air and fuel in a combustor.
