Experimental Investigation of Stability and Transition of Flow Between Two Rotating Disks

不稳定性保存和过渡到湍流将是 实验研究的旋转之间的流动限制 磁盘。 常规和非牛顿流体（通过聚合物 将用于探索非定常流动模式， 特性，使用流动可视化技术（薄片 悬浮液）和定量速度测量LDV（激光- 多普勒测速仪）。 待研究的流量为 关于离心效应和曲率的基本兴趣，以及 也与润滑和粘度计有关， 牛顿和非牛顿流体的性质。

Instability saves and transition to turbulence are to be experimentally investigated for flows confined between rotating disks. Both conventional and non-Newtonian fluids (through polymer addition) will be utilized to explore unsteady flow modes and characteristics, using flow visualization techniques (flake suspensions) and quantitative velocity measurements from LDV (Laser- Doppler Velocimeter). The flows to be investigated are of fundamental interest regarding centrifugal effects and curvature, and are also relevant to lubrication and viscometers used to determine Newtonian and non-Newtonian fluid properties.
