Numerical Simulation of an Ultra-compact Interstage Turbine Burner with Circumferential Struct
Download citation file:
The conventional Ultra-compact Combustor (UCC) has obvious temperature distortion at the outlet section, which adversely affects the low-pressure turbine rotor blade working in the Interstage Turbine Burner(ITB). In order to solve this problem, the addition of a circumferential struct located on the upstream channel in the circumferential cavity. Disturbance occurs when the main airflow flows through the circumferential struct, enhance the main airflow and circumferential cavity combustion mixture mixing, make combustion reactions more complete, promote high temperature airflow in the circumferential cavity flowing into the main airflow and improve the outlet temperature field. Numerical simulations were conducted on an UCC...
