WANG Wei-jian, DU Shang-ming, ZHANG Rong-chun, et al. Experiment on overall temperature distribution of the inter-stage turbine double vortex combustor[J]. 2012, 27(2).DOI:
the influential factors of overall temperature distribution in the double vortex combustor were studied experimentally.The results of experiments were obtained showed that:(1) With the Mach number Ma of mainstream increase
the overall temperature distribution factor (OTDF) decrease.(2) The mainstream temperature has great impact on the overall temperature distribution
the OTDF decrease with the increase of mainstream temperature.(3) With the excess air coefficient increase
the OTDF increase firstly and then level off or decrease.(4) Different cavity structures have a great impact on the OTDF
after compare several test pieces
the piece which the aspect ratio is 0.8
the after-body intake is slot air intake could achieve the best OTDF.
