Performance contrast experiment of prototype single cascade and redesign tandem cascade at high inlet Mach number

  • 摘要: 基于某高负荷轴流风扇高临界来流马赫数静叶改型设计的需求,对原型单列叶栅和改型串列叶栅开展性能对比试验研究,通过详细分析两型叶栅内部流场参数,量化评估了串列叶栅在高来流马赫数条件下的改进设计效果.结果表明:串列叶栅比单列叶栅在降低流动损失,提升增压能力方面具有显著优势.相比单列叶栅,设计状态下串列叶栅总压损失系数降低了19%,静压比提高了3.1%,基本缓解了单列叶栅原有设计状态的流动堵塞现象.串列叶栅前排叶片对后排叶片吸力面附面层发展会产生抑制作用,使得后排叶片具有较好的工作性能.
