| 摘 要： | 通过均匀搅拌器(PSR)模型研究了某型燃气轮机燃烧室入口流动参数脉动对燃烧不稳定的影响.研究结果表明:对于贫预混燃烧室(燃烧室工作在较低的入口当量比下)来说,当入口温度、入口气体流量和入口当量比的相对脉动幅值相同时,入口当量比的脉动对燃烧不稳定性的影响最大,其次是入口气体流量,而入口温度的脉动对燃烧不稳定性的影响相对较小.

| Abstract: | The effects of inlet flow parameters oscillation on combustion instabilities of a gas turbine combustor were studied by introducing perfectly stirred reactor (PSR) model. The simulation results demonstrate that, for lean premixed combustor (combustor operating at low inlet equivalence ratio), when the relative oscillation amplitudes of inlet temperature, inlet mixture mass flow rate and inlet equivalence ratio are the same, the oscillation of inlet equivalence ratio has the largest effect on combustion instability phenomenon, then followed by inlet mixture mass flow rate, and the inlet temperature yields the lowest effect. |
