摘要

由于燃烧区和壁面的距离过近

驻涡燃烧室壁温过高的问题一直存在

影响其在实际发动机上的应用.对某涡轮级间驻涡燃烧室进行壁温分布试验研究

研究供油量、主流进气参数对壁温分布的影响

并考察燃烧室的冷却和进气结构是否合理.试验结果表明

试验件的最高壁温出现在凹腔后壁面;供油量和主流马赫数对试验件的壁温分布趋势影响较大

主流温度对壁温分布趋势的影响较小.

Abstract

Because the distance between combustion zone and wall is very short

the overhigh wall temperature is a longstanding problem of trapped vortex combustor(TVC)

which limits the actual application of TVC.The experimental study of wall temperature distribution on the TVC was reported in the paper

and the influences of fuel supply quantity and inlet parameters of main stream on the wall temperature distribution were investigated.Meanwhile

the rationality of cooling structure and air jet entrance structure was analyzed.The test results show that the hot spot temperature of combustor appears in the after-wall.The distribution of wall temperature is greatly influenced by the fuel supply quantity and the mach number of main stream

but little influenced by the temperature of main stream.
