【摘要】 本文介绍了一种带有中心射流、轴向旋流器的预燃室内冷态流场的试验研究结果，以及旋流数、风量、中心射流等对流场内轴向、切向、径向速度分布，回流区大小，压力场及回流率的影响，对预燃式烧嘴的设计有一定的参考价值。更多还原

【Abstract】 he experimental results from cold flow field of pre-burning chamber with central spraying and axial flow rotator were discussed as well as the effect of the number of rotatory flows, wind volume,central spraying etc on axial, tangent, radial speed distribution,the size of circulating zone,pressure field and circulating ratio, which is worth while designing pre-burning burner.更多还原
