摘要: 一、前言 从1977年开始,在某环管燃烧室上开展了对抽气控制旋涡式短突扩扩压器(简称抽气短突扩)的冷吹风试验研究。采用双壁抽气控制旋涡,进行了有关几何尺寸和气动参数对扩压器性能影响的研究,取得了一些成果。 本研究是在上述工作的基础上,选取性能较好的一种结构方案,考察采用抽气短突扩的燃烧室的主要性能,以及抽气方式和抽气量对燃烧室出口温度场、燃烧效率、排气污染和冒烟等的影响。

Abstract: An experimental study was made of a tubo-annular combustor with a vortex-controlled dump diffuser by bleeding air on 36-degree sector test-pieces. All combustion performance was investigated including exit temperature pattern, combustion efficiency exhaust emission and smoke number. Comparing with the performance of original combustor using dynamic diffuser, the new type diffuser is effective.
