摘要(Abstract)：
采用数值模拟的方法,研究了引气对某双级轴流压气机气动性能的影响。数值计算所获得实壁机匣总性能与试验结果符合良好,结果表明,在靠近第二级转子前缘处的机匣引气能够有效地提高压气机的失速裕度的同时,对压气机的压比和效率影响较小,分析了引气对压气机顶部区域流场结构的影响。
Bleeding are known as a powerful method to enhance the flow stability in compressors.The effect of bleeding on the performance of a two-stage axial-flow compressor was performed with the help of numerical method.The numerical results agreed well with experimental test data for the global performance of smooth wall.In addition,the numerical results showed that bleeding near the rotor leading edge of second stage can significant extend the operating range of compressor with minimal or no loss in efficiency and total pressure ratio.The effect of the bleeding on tip flow topologies was analyzed.
