Abstract: 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).
