    Abstract
  • With use of the parametric modeling method, when the size of diffuser, the maximum dimension of outer case and exit size of combustor were kept the same as single annular combustor (SAC), the combustor head swirler was redesigned from the double-swirler structure into triple-swirler structure; the three-dimensional flow and combustion processes of double-swirler combustor (TSC) and triple-swirler combustor (TSC) were numerically simulated, and the performance of two high temperature rise combustors were compared. The results indicate that, the traditional DSC cannot meet performance requirement such as combustion efficiency of high temperature rise combustion with fuel air ratio of 0.037; by using the TSC, the total pressure recovery coefficient, combustion efficiency and temperature rise can be improved compared with the DSC; the outlet temperature distribution factor (OTDF) and radial outlet temperature distribution factor (RTDF) of TSC is lower than that of DSC. With fuel air ratio of 0.037, the total pressure drop of designed high temperature rise TSC is less than 5%, OTDF reaching 0.162, RTDF reaching 0.106, and combustion efficiency is more than 99%.
