摘要:
为提高潮流能装置发电功率及可靠性,加快潮流能开发利用,本文提出了一种Π型竖轴双转子水轮机的设计,并对Π型竖轴双转子水轮机的纵荡运动特性进行了研究。基于CFD方法,通过将水轮机旋转运动与振荡运动相结合的方法模拟水轮机的纵荡运动,对竖轴双转子水轮机在不同振荡频率、振荡幅值及叶尖速比下的纵荡运动进行模拟计算,同时与均匀流无振荡工况下的水轮机作对比,分别对振荡运动下双转子水轮机受力、获能效率及流场的变化特征进行分析。研究结果表明:双转子并列布置可提高水轮机获能效率、纵荡幅值及频率对平均获能效率影响较小。纵荡下双转子水轮机所受推力及侧向力的波动较大,且推力及侧向力波动幅值与振幅及振荡频率成正比。振荡频率影响泄涡频率,振荡幅值影响尾涡区长度。
