Abstract: In order to change a Single Annular Combustor(SAC) into a Dual Annular Combustor(DAC),the authors kept the diffuser,outer case and atomize of the SAC unchanged,redesigned the combustor from a single annular structure into a dual annular structure,and designed six different structure DAC.Taking the same physical models(including the turbulence,radiation,spray and emission models),simulations of three dimensional two-phase reacting turbulent flow in both the SAC and DAC were developed in the Fluent Code.The  total-pressure recovery coefficient,temperature distribution and exhaust emission levels were given.Finally,by comparing the simulation results,the feasibility of displacing the SAC into DAC structure  was certified.

Key words: combustors design;single annular combustor;dual annular combustor;combustion , simulation
