本文基于有关试验的结果采用了一个“激盘-滞后-容积”模型作为压气机级的物理模型,以代替近年来常用的“激盘-集聚容积”模型。为了比较,在数字机上分别用这两种模型预算了一台多级轴流压气机的失速线。模拟的证实除了和部件试验结果比较外,还专门在发动机试验台上作了逼喘试验。结果表明,用新模型得出的失速线和全台试验得出的几个失速点很接近,而用旧模型预算的失速线恰位于部件失速线的右下方。这种过早预示工作不稳定的情况,在前人所作的稳定性模拟中也可以发现,这表明新模型改进了模拟效果。 在模拟稳定性的同时,也模拟了非设计工况下级间的相互匹配,所得的等转速线和试验数据也较符合。 Based on the results of the experiments, a plateau-lag-volume model was used as a compressor-level physical model instead of the plate-accumulating volume model commonly used in recent years. For comparison, the two models were used to estimate the stall line of a multistage axial-flow compressor on a digital machine. In addition to the simulation and component test results in addition to comparison, but also specifically on the engine test bed made a push-out test. The results show that the stall lines obtained by the new model are close to those obtained by the whole station test, while the stall line estimated by the old model is just below the stall line of the part. This premature instability of work is also evidenced by previous stability simulations, which show that the new model improves the simulation. Simultaneously with the simulation stability, the mutual matching between lower and lower stages in non-design conditions was also simulated, and the obtained equal-speed lines and test data are more consistent.
