| 摘 要： | 为了研究双涵道风扇／增压级的设计与非设计状态性能，利用三维数值模拟软件对某型双涵道风扇／增压级80％设计转速、88％设计转速、96％设计转速、100％设计转速下的各种工作状态进行了数值模拟。重点分析了典型工况下风扇／增压级出口特性参数分布与非设计转速下内涵特性。同时通过和实验结果的比较表明，对风扇／增压级设计状态性能的模拟较非设计状态性能的模拟更为准确。

| Abstract: | A three dimensional numerical simulation software named NUMECA(Numerical Mechanics Application)was used to calculate different operating points at 80%,88%,96% and 100% design speed to study design and off-design performance of fan/compressor.The characteristic parameter distribution at outlet under typical operating condition and off-design performance of core duct were analyzed.Compared with the results obtained from experimental data,the numerical simulation of fan/compressor design performance at design operating point show better agreement with the experiment than off-design operating point. |
