Combustion Captibility Comparison of Single Annular Combustor and Dual Annular Combustor
摘要
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.关键词
