Abstract:The air flow distribution in a designed single tube combustor (for 100kW ground gas turbine) was experimentally investigated. Under the atmospheric pressure condition, the flow distribution characteristics of the swirlers, primary holes and dilution holes were experimentally obtained using hole plugging method separately, and the discharge coefficients for different structures were analyzed based on the experimental data. Then the flow distribution and total pressure loss of the single tube combustor were studied under different inlet air flows. Results showed that the air flow distributions of different structures were stable when the inlet air flow varied, and agreed very well with the designed data. With the increase of the inlet air flow (inlet Reynolds number), the discharge coefficients for swirlers, primary holes and dilution holes decreased slightly, but the total pressure loss increased gradually. The experimental results of primary holes and dilution holes by using two flow distribution experiment methods were slightly different but basically the same for the air distribution, therefore, the two different experiment methods were reliable. The experimental results can provide an optimization basis for the design of 100kW ground gas turbine single tube combustor. © 2018, Editorial Department of Journal of Aerospace Power.
