| 中文摘要: |
| 间冷循环可使燃气轮机功率提高且耗油率降低，但由于间冷的介入，燃烧室的喷油量和容热负荷会大幅增加，这必然导致燃烧室性能的恶化。采用数值模拟的方法，对比研究了在标准工况和间冷后增容工况下燃烧室冷态流场和燃烧性能的差异，并提出组合涡诱导结构以解决间冷给燃烧室带来的问题。结果表明：间冷后压力损失增加了135%，燃烧后高温区偏心严重，燃烧效率、出口温度分布系数等明显降低；使用组合涡诱导控制结构后燃烧效率可提高1.6%，且出口温度分布改善明显。 |
| 英文摘要: |
| Intercooled Cycle （IC）could enhance the power of gas turbine and decrease the fuel consumption. Provided the intervening of IC，it increases fuel-injection quantity and volumetric heat intensity, and it leads to bad performance of the combustor. Cold flow field and combustion performance of standard condition and capacity-increase condition were compared with numerical simulation methods. And then combined vortex induced device to solve aforementioned problems were given. The result shows that under IC condition，once pressure loss increases 135%，high-temperature region is eccentric，and combustion efficiency and outlet temperature distribution factor are decreasing. Using combined vortex induced device，the combustion efficiency was increased 1.6%，and outlet temperature distribution was improved obviously. |
