Windage measurements for rotating disc with protrusions

  • 摘要: 为研究壁面不同粗糙程度以及带有螺栓等表面凸起的转盘风阻扭矩特性,建立了一个转盘扭矩测量实验台.自由盘测量结果与经典经验关系式较好的符合度验证了测量方法的准确性.分析研究了在不同粗糙度以及附有6种凸起结构的转盘风阻扭矩规律.结果表明,壁面的粗糙会增大转盘受到的扭矩,在所测量旋转雷诺数范围内,从气动光滑一直到粗糙高度0.2 mm,扭矩系数增大1倍.基于气动光滑自由盘经验关系式进一步总结出相对粗糙度对于风阻扭矩的影响系数.对比6种凸起引起的风阻扭矩特性发现,叶型凸起会大幅降低风阻扭矩.凸起安装迎风角度的改变会带来10%的风阻扭矩差别.结合自由光滑盘扭矩系数经验关系式,总结出不同凸起形状对于扭矩系数的影响因数.
