| 摘要: |
| 以NASA Rotor35为研究对象,应用数值模拟手段深入分析了叶表和端壁不同位置抽吸对该压气机稳定性的影响效应。研究结果表明:叶表抽吸虽然使得压气机压比和效率有所升高,但使叶顶前缘脱体激波和间隙泄漏流强度的增加,导致两者相互作用引起的低能堵塞团尺度过早增长,压气机提前进入失速;端壁抽吸改善了转子顶部前缘激波结构,削弱了叶顶低能阻塞团中的高熵流体,改善了叶顶区域的流动,实现了压气机的扩稳效果,但对压气机压比和效率性能改善不明显。 |

| Abstract: |
| Sections 1 and 2 of the full paper explain the comparison mentioned in the title. Their core consists of:with the numerical simulation method, we compare the effects of the blade surface suction with those of end-wallsuction on the stability of the transonic compressor with NASA Rotor 35; Fig. 1 in section 2 gives the schematic di-agram of the BLS. Subsection 3. 1 analyzes the effects of the blade surface suction on the stability of the compres-sor; subsection 3. 2 analyzes the effects of the end-wall suction on the stability of the compressor; then they makecomparison of the analysis results. The comparison results, given in Figs. 2 through 7, and their analysis show pre-liminarily that: (1) the blade surface suction improves the pressure ratio and efficiency of the compressor but maystrengthen the shock wave and tip clearance flow, causing the lower energy blockage flow to grow too early; the ear-ly growth of the lower energy blockage flow may lead to the instability of the compressor; (2) the end-wall suctionchanges the shock wave structure near the front edge of the rotor tip, reduces the lower energy blockage and im-proves the flow of the blade tip region, thus enhancing the stability of the compressor; however, the end-wall suc-tion can not greatly improve the compressor’ s pressure ratio and efficiency. |
