超紧凑燃烧室燃烧组织方式影响燃烧性能的数值研究
Numerical studies of combustion mode influence on the performance of UCC combustor
摘要
Abstract
Taking the design testing model of UCC combustor as the research object,numerical simulation of high speed rotating turbulent flow is conducted with Realizable k-ε turbulence model,so is simulation of combustion reaction with non-premixed PDF combustion model. Through the comparison and analysis of the combustion performance such as temperature distribution,quality of outlet temperature field,combustion effi-ciency and pollutant emission under three different combustion modes like the lean-fuel combustion,the stoi-chiometric ratio combustion and rich-fuel combustion,the influence of combustion mode on the performance of ultra-compact combustor is examined. Lean combustion mode has a greater impact on the combustion in the cavity. In the rich-fuel combustion,flame connected in the bottom of the cavity and mixed with the pri-mary air stream through the radial chute,and complete combustion was achieved. Combustion efficiency, quality of outlet temperature field and pollutant emission are better in lean-fuel combustion mode. The results are consistent well with other similar studies in the combustor center area,and have referential value to the UCC combustor design.关键词
