基于双旋流全环燃烧室的出口温度分布试验研究

The double swirler full annual combustor was taken as the experiment object, the outlet temperature distribution under different experiment conditions was compared and analyzed under high temperature/high pressure, high temperature/medium pressure and engine experiment conditions. The experimental schemes with annular bleed and simulated nozzle were designed to simulate the boundary conditions of the engine, and the outlet temperature distribution under different experimental conditions was analyzed. The experimental results showed that the outlet temperature distribution under the medium and high pressure experimental conditions was basically the same, and the hot spot area was basically the same; the outlet temperature distribution level of the middle pressure experiment was obviously better than that of the high- pressure experiment; the temperature distribution curve of high-pressure experiment was in the form of central peak, while that of medium pressure experiment was not obvious. The designed high-pressure experiment outlet temperature distribution law and value were closer to the engine experiment results; compared with the high-pressure experiment, the outlet temperature distribution value of the medium pressure experiment designed regularly had a proportional coefficient of 1.3—1.4.
