摘要
本文探讨不同离心力分布对旋流加力室性能的影响.对模型的流体阻力、温度分布和燃烧效率进行了试验研究.旋流器出口的四种切向速度分布为:Rankine涡、强迫涡、自由涡和常数角涡.试验表明:出口为Rankine涡的旋流器,其流体阻力最小;在由离心力组织燃烧的加力室模型中,即使在小旋流数下(S=0.25)
This paper discribes the investigation on the effect of centrifugal force distributions on swirl augmentor performance. The experiment investigation are conducted on the flow drag,temperature distribution efficiency in the swirl augmentor model with different tangential velocity profiles.Four tangential velocity distributions considered are Rankine vortex,forced vortex, free vortex and constant angle vortex.The experiment results show that the flow drag of Rankine vortex swirler is the smallest one,and in a swirl augmentor where flame is stabilized by using centrifugal force,the combustion efficiency can still reach 90% or over,though the swirl number is low(S= 0.25).
