Open publisher page 0 citations

Abstract

Numerical simulation of the performance of QD128 gas turbine combustor was finished using CFD method. The results indicate: The flow meter distribution of combustor is reasonable, and the velocity field of combustor meets the design requirements. Outlet average temperature is 1298K, hot spot temperature is 1486K, the temperature distribution curve meets the design requirements, and OTDF=0.280，RTDF=0.086，which are slightly higher than the level of prototype aircrafts. The results enrich the design data of QD128 gas turbine, and provide reliable reference for the running and improving.
