The prediction of combustion efficiency at different downstream locations of the flame stabilizer is an important problem in the length design of afterburner. Taking the upstream-injection U-shaped bluff-body flame stabilizer as the research object, a prediction model of the combustion efficiency downstream the flame holder in the afterburner based on reaction rate controlling was proposed and verified by the combination of numerical simulation and theoretical analysis, under the conditions of incoming flow temperature of 600—900 K, incoming flow velocity of 75—170 m/s and equivalent ratio of 0.22—1.20. At the same time, the prediction model of turbulent flame velocity and the semi-empirical prediction formula of turbulent intensity for afterburner were determined. The results showed that compared with the numerical simulation results, the prediction errors of the model for the combustion efficiency at different downstream locations of the flame stabilizer were less than 2.5% at different incoming temperatures and velocities, and less than 20% at different equivalent ratios.
