【摘要】 采用以试验为基础的二元方法配之三元校算,设计出了性能优良并满足预定技术要求的某型低压压气机。全台试验结果表明,这台压气机未经调整,其流量、压比、效率已经达到了设计指标,优选工作点后性能更佳,压气机低工况性能好,有可用的稳定工作范围,出口流场均匀。更多还原

【Abstract】 By adopting a test-based two-dimensional method coupled with three-dimen-sional verification calculations a high-quality lowpressure compressor with char-acteristics capable of satisfying preset technical requirements has been successfu-lly designed,The test results of the compressor as a whole have shown that thecompressor without any further adjustment can attain all design objectives inrespect of flow rate,pressure ratio and efficiency.With operating points beingoptimized it is possible to achieve an even better performance.The compressorfeatures good working characteristics when operating at low load conditions,a relatively wide range of stable operation and an uniform outlet flow field.更多还原
