喷嘴特性对双旋流燃烧室出口温度分布影响的实验研究

Using the double swirl full annual combustor as the test object，under the condition of high temperature and pressure test，the effects on the double swirl full annual combustor outlet temperature distribution quality were evaluated by adjusting the fuel flow dispersion and radial position.The test results show that when the fuel flow dispersion of the nozzle is controlled within ±4%，the outlet temperature distribution can be ensured by using the alternative matching scheme of simple large and small flow nozzle positions.When the dispersion is amplified within 4%~8%，the distribution can still be ensured by using the location scheme of experimental research. When the dispersion is amplified to 10%，the distribution cannot be guaranteed by adjusting the nozzle position. When the radial position of the fuel nozzle deviates from the center line of dome by less than 11.5% from the height of the swirl cup cavity，the outlet temperature distribution quality would not be affected.
