摘要: 为满足高效、高负荷、高可靠性大流量轴流涡轮的应用需求,涡轮叶片的长度和展弦比设计日益增大。相较于较短的叶片,长叶片沿径向的叶型以及气流参数分布的变化幅度更大,因此其设计要求更高。受涡轮负荷需求、环境条件等因素变化的影响,长叶片往往变工况运行,其级内三维流场结构复杂,各项性能恶化,容易导致叶片的安全性及使用寿命下降。为方便学者后续进一步研究长叶片级在变工况运行时的气动、传热与结构强度特点,探索拓宽长叶片级高效、稳定运行范围的方法,梳理了该领域近年来的研究成果。首先介绍长叶片的气动与结构设计特点,再分析与总结变工况时长叶片级的气动特性、传热与强度特性,并简述排气装置对末级长叶片内部流场的影响,最后分析目前仍存在的不足,展望轴流涡轮长叶片级在控制变工况不利影响方面与优化设计方面的未来发展趋势。
